Show HN: wasque – Lightweight Cloudlare Warp Proxy Container for Linux https://ift.tt/KkQSwV6

Show HN: wasque – Lightweight Cloudlare Warp Proxy Container for Linux Lightweight, unofficial Docker container for the official Cloudflare WARP Linux CLI client. Easily expose a SOCKS5 proxy from within a container—no elevated privileges required! My previous project unofficial WARP client, usque ( https://ift.tt/MCumVLd ) got great reception so far and Cloudflare recently published HTTP/2 fallback support on their MASQUE protocol. I needed a way to run their official clients in a reproducible, lightweight fashion so that's when wasque was born. It's a really simple docker container that ships their official client and exposes it as a SOCKS5 proxy. PS: For now the HTTP/2 fallback seems broken for me in their official Linux and Android clients, I already opened a ticket ( https://ift.tt/ey1z7BA... ). But regular HTTP/3 MASQUE works well. https://ift.tt/pTUWu9w June 20, 2025 at 11:11PM

Show HN: Inspect and extract files from MSI installers directly in your browser https://ift.tt/jx1CAhW

Show HN: Inspect and extract files from MSI installers directly in your browser Hey everyone! I'm excited to share a small web app I built that allows you to view and extract the contents of Windows MSI installers directly in your browser. It's essentially a web-based "lessmsi" powered by Pyodide. You can try it out at: https://ift.tt/WH6Yfoc My motivation for building this was from part of my day job -- I often get Windows MSI installers and need to extract files while preserving the relative directory structure and filenames, as they would appear after a full installation. The existing tools I found were good but limited in which platforms they support: lessmsi works great on Windows, while msitools works for Linux/macOS. Neither is a truly cross-platform solution that works on any major OS. So we developed pymsi (a pure Python library, available on GitHub at https://ift.tt/67r5G0d ) to handle reading and extracting MSI files from Python. Then I realized that since pymsi has no native dependencies, it could potentially run in a web browser using Pyodide. After a bit of "vibe coding" and fixing some "hallucinated" functions/classes that don't exist in pymsi, the result was this client-side web app. If you need an MSI file to experiment with, older versions of PowerToys included the installer in .msi form, such as this one: https://ift.tt/LuKJ7Ai.... Note that the underlying pymsi library hasn't been extensively tested against a bunch of MSI installers yet, so there might still be lingering bugs. If you come across any issues, please don't hesitate to report them in on the GitHub repository ( https://ift.tt/iJHhmS1 ). I'd love to hear your feedback and answer any questions! https://ift.tt/WH6Yfoc June 21, 2025 at 12:04AM

Show HN: RM2000 Tape Recorder, an audio sampler for macOS https://ift.tt/w32THXo

Show HN: RM2000 Tape Recorder, an audio sampler for macOS RM2000 Tape Recorder makes it stupid simple to grab audio samples and organize them: just record the sample, give it a title (and maybe some tags), and it is saved neatly into a directory of your choosing. I'm a huge datahoarder and have always appreciated tools / services like PureRef and Are.na which help me make sense of everything I collect. Those services concern themselves with images and video - I wondered, why can't the same be done with music and audiofiles? I actually got the inspiration for the filenaming scheme from the Emacs Denote package - every sample is saved in the format of title--tag1--tag2.mp3. Emacs Denote does something similar, for example an identifier--title--keywords.org . I chose this method as any file browser with fuzzy search can search through samples, i.e. - the Ableton file browser. Just search up some of the tags, and a title, and you'll be able to find your sample. I wanted this app to look good, as well (and is why I spent so much time making it!) The app is made with a mix of SwiftUI and AppKit, while the assets were rendered in Sketch I appreciate your time and I'd love to hear your thoughts on it. If you do download it, and find suggestions / bugs, please let me know! Cheers https://rm2000.app June 17, 2025 at 08:20PM

Show HN: AI Debate Arena – See Which LLM Argues Best https://ift.tt/xvpG7bO

Show HN: AI Debate Arena – See Which LLM Argues Best Ever wish you could get the best arguments for both sides of a debate? I built an AI-powered debate platform that pits language models against each other on controversial topics. Each AI is randomly assigned a side (pro/con). You vote before and after to see if you were persuaded. Most content today presents lopsided arguments. They provide strong points for one side, weak ones for the other. This project aims to surface the strongest arguments from both sides, using LLMs to simulate a fair debate. With enough usage, I want to use it to benchmark LLMs. My hypothesis is that randomly assigning sides of the debate, models with built-in biases will score worse. It’s currently using GPT 4o, Grok 3, and Gemini 2.5 Flash. It’s early, still rough around the edges, and I’d love feedback on the concept and direction. Curious how the HN crowd thinks this could evolve. It’s built for the intellectually curious that are open minded about changing their positions. Some next steps I’m considering: - Tuning the length and structure of arguments - Prompting improvements to reduce rhetorical fluff - Optional audio output of debates Try it out and let me know what you think! https://ift.tt/fCKS1Ei June 19, 2025 at 12:26AM

Show HN: I built a FOSS tool to run your Steam games in the Cloud I wanted to play my Steam games but my aging PC couldn’t keep up, so I built Cloudy Pad - a tool to run Steam in the Cloud (GitHub: https://ift.tt/36M5EYs ) It runs on AWS, Azure, GCP, Scaleway and Paperspace with various cost optimizations and safeties: - Cost alerts - Auto stop inactive instances to avoid unwanted cost - Disk snapshots and data cleanup for cost efficiency - Spot instance support Under the hood: a Linux VM and a container running Sunshine (a streaming server https://ift.tt/hoaEOWc ) with Steam. Most Windows games work just fine thanks to Proton. It streams effortlessly at 1080p 100+ FPS - I recently played Baldur’s Gate III and Clair Obscur in Ultra, ran like a breeze. Cost-wise it’s great for occasional players: ~30h or less per month typically cost less than 25$. Though admittedly for heavy gamers it may be less cost-effective due to cloud pricing. I’d love feedback from the HN community ! https://ift.tt/36M5EYs June 17, 2025 at 10:57PM

Show HN: Personalized Wealth Management – Institutional Meets Consumer https://ift.tt/tMKu9fv

Show HN: Personalized Wealth Management – Institutional Meets Consumer Problem: If you have less than $100k to invest, you get a robo-advisor that asks you 5 questions and dumps you into one of three cookie-cutter portfolios. If you have more than $100k, you get a human advisor who charges 1-1.5% annually to... basically do the same thing with a smile and calming voice attached. Meanwhile, institutional investors get custom strategies built around specific durations, target dates, tax situations and actual investment goals. Not because the math is harder—but because the economics only work at scale. Here's the thing: Both traditional advisors and robo-advisors maximize profit by minimizing choice and directing capital into the bias strategies that generate them additional margins. Both just tweak a risk slider and call it "personalization." But institutional-grade portfolio construction doesn't have to be exclusive to the wealthy. The road was paved by platforms like Plaid, brining API connectivity—platforms and asset aggregation into the mainstream. Modern AI completes the picture by making true personalization economically viable via "micro-advise". No asset transfers, no new custodians, just sophisticated strategies based on your financial goals executed where you already invest coupled with personalized financial planning & budgeting. Technical Solution: We've built our MVP wealth management platform that creates truly personalized portfolios by combining institutional capital market expectations stemming 30+ global asset classes. All available through low-fee publicly available ETFs. Our approach: - SEC licensed & compliant Registered Investment Advisor - Generates unlimited unique portfolio combinations optimized for risk, return & goal specifics. - Personalizes to individual goals, not generic risk buckets. - Learns and improves from every user interaction - Provides institutional-grade sophistication without human bottlenecks - Removes manager bias for in-house strategies - Uses a "glidepath" approach similar to the US retirement target-date structure to maximize achievement certainty of important life goals (down-payment, retirement, etc) - Seeks to bring elements of habit forming platforms (like Duolingo) into retail wealth. Business Model Innovation: -Non-custodial + AI architecture enables subscription pricing ($10/month) instead of AUM fees. Users keep control of assets while getting personalized institutional strategies. Research Validation: - Glidepath strategies delivered higher values in 76% of scenarios (T. Rowe Price) - Global diversification outperformed domestic-only in 96% of 3-year periods (Hübner) - Chance of success metrics for significant life goals like retirement & major milestones are measurably improved via behavioral advantages & sequence risk protection (T. Rowe Price). Early Results: -Alpha users report 90%+ cost reduction vs. traditional platforms with superior personalization. Institutional style portfolios achieving goal-specific optimization that would cost minimum 10x elsewhere. -Base model portfolios have outperformed comparable portfolios from existing market incumbent robo-platforms on both an absolute & risk adjusted basis in H1 2025. What's Different: This isn't another robo-advisor using basic mean reversion. It's personalization that helps you understands and discover your specific goals and adapts continuously. Think "personal wealth manager in your pocket" rather than "generic portfolio assignment." All that, in a consumer product platform designed to empower retail investors and keep them engaged. Next Steps: Currently in invite-only alpha at www.fulfilledwealth.co. We focused early on the portfolio construction & delivery process and are now building out the consumer-facing aspects of the web application. Looking for feedback from the HN community on our approaches to financial personalization. https://ift.tt/WtEmMT7 June 16, 2025 at 02:58AM

Show HN: Seastar – Build and dependency manager for C/C++ with Cargo's features https://ift.tt/Oa41Jck

Show HN: Seastar – Build and dependency manager for C/C++ with Cargo's features Hi hackers! I'm a self-taught solo teenage dev working on Seastar, a unified build system and dependency manager for C and C++. It is capable of compiling and linking projects, managing recursive dependencies and headers, and even has a template system -- your C++ library is one `seastar new mylib --lang c++ --lib` away! Also, everything is configured in TOML, because TOML is awesome. *But why?* C is one of my favorite languages, but I usually end up writing stuff in Rust because I love Cargo. Unlike C, Cargo handles the dependencies, linking, globbing, and so much more for you. So I wrote Seastar to give that function in C and C++. *What's planned?* A package registry like crates.io, compatibility with CMake projects, commands to migrate, and so much more. If you have more ideas, please give them! I am trying to reach 150 stars by the end of summer, and thus a star would be greatly appreciated! This project is still in development, and a star helps out a ton. https://ift.tt/q8fVwcU June 15, 2025 at 11:36PM

Show HN: Gem and I built an open-source app to learn Japanese https://ift.tt/npfC2Aq

Show HN: Gem and I built an open-source app to learn Japanese I've been fascinated by the Japanese language and culture for a while now, and I wanted to create a simple, no-fuss way for beginners to get started. So, I built *[Nihongo]( https://nihongo.site/ )*, a free and open-source web app designed to help you learn the fundamentals of Japanese in about a month. The name of the app, Nihongo (日本語), is the Japanese word for the "Japanese language." You can check it out here: *[ https://nihongo.site/ ]( https://nihongo.site/ )* And for those who like to tinker, the code is available on GitHub: *[ https://ift.tt/lOgkSqB ]( https://ift.tt/lOgkSqB )* The "learn in 30 days" idea isn't about achieving fluency in a month, which we all know is impossible. Instead, the goal is to provide a structured and manageable learning path that covers the essential building blocks of the language in a short period. I wanted to create something that feels less intimidating than many comprehensive (and often expensive) resources out there. *What the app covers:* The app is structured into a series of lessons that you can follow at your own pace. It starts with the absolute basics and gradually introduces more complex concepts: * *The Japanese Writing Systems:* Detailed lessons on Hiragana and Katakana, the two phonetic scripts that are the foundation of written Japanese. * *Essential Grammar:* I've focused on the core grammatical structures you need to start forming your own sentences. * *Core Vocabulary:* You'll learn a curated list of high-frequency words that are immediately useful in everyday conversation. * *Practical Phrases:* The app includes common greetings and phrases that you can start using right away. *Why I built this:* I started building this project while testing the latest Gemini 2.5 models on Google AI Studio, and with the Code assistant and Cloud Run I was able to get it to production in less than 3 hours. This as a personal project to solidify my own understanding of Japanese and to build something useful for others who are just starting their learning journey. I'm a big believer in the power of open-source and wanted to create a resource that is accessible to everyone. This is very much a passion project, and I'm still actively working on it. I'd love to get your feedback, suggestions, and of course, any contributions on GitHub are more than welcome. Let me know what you think! I'm here to answer any questions you might have. https://nihongo.site June 14, 2025 at 03:04AM

Show HN: I rebuilt the recruitment process from the ground up https://ift.tt/y2qcX1D

Show HN: I rebuilt the recruitment process from the ground up Hi HN Community, Recruitment software is everywhere. The market seems saturated. Every other day there’s a new ATS or “all-in-one” platform promising to fix hiring. But let’s be real — recruiting still sucks. Why? Because most tools are just reskinned versions of the same broken process: resume parsing, email campaigns, messy workflows, and outdated data. Some throw in a ChatGPT prompt here and there and call it “AI-powered.” But if we’re still stuck in the same flawed flow, it doesn't matter how modern the UI is. I’ve felt this pain personally — both as a recruiter and a job seeker. That's why I built Chronoflow — not just another ATS, but a reimagined recruitment system that actually works. --What makes it different: No resume parsing. No data entry. Candidate pools build themselves as soon as someone accepts your job invite. --No email campaigns. You already have the latest candidate data, and the platform shows you exactly who to engage. --No endless back-and-forth. Job invites include everything — replacing pre-screening calls and endless follow-ups. --Candidates get live updates and AI-generated feedback if rejected — improving their experience and keeping your brand strong. --Recruiters focus on decision making and building relationships, which is important for business development. Chronoflow is built for people who are tired of trying “yet another ATS” that solves 10% of the problem. If you're curious to see what a rebuilt hiring cycle looks like that drastically reduces time to hire and on top of that makes recruitment transparent and enjoyable, I'd love for you to give Chronoflow a try. Happy to answer any questions. And if you've worked in recruiting, would love to hear what frustrates you most — maybe I can solve that too. Thank You https://chronoflow.ai/ June 12, 2025 at 11:04PM

Show HN: AuraCoder – Gen AI Learning Platform https://ift.tt/4JEPvSa

Show HN: AuraCoder – Gen AI Learning Platform Hey HN, I've been pouring my time into this side project and I think I finally got an MVP up! I'm really excited about it. I'm really passionate about combining LLMs and learning. It seems like one of the best firsts for the tech. And so I built a site where all the content is generated. As I've been building, I'm always torn between building something more general purpose where you can learn anything vs building something targeted where the generation can be more tailored. Currently, its the latter so the site is focused on data structures and algorithms. That's something I've ground out recently so just familiar with what good content might look like and it was helpful in getting the prompt engineering to generate decent content. The site can generate both Lessons and Challenges. And they are a bit tailored to you. You can set settings about what kind of preferences you have. Tone of voice, depth, even an open text that gets feed into the prompt. I tried "Include a cat joke in every lesson" and I thought that was pretty entertaining It also takes into account your current skill level on different concepts. But I also think I need to lean in more on the customization. That seems to be the biggest way AI generated content can differentiate. I think its been hard to generate content that's really as good as human expert generated stuff, but it can be tailored to the user. So really interested in ideas in that vein. And in general, any advice is greatly welcomed. Also of course willing to AMA. Happy to answer any questions about the tech stack, the apps architecture, etc Sorry the site requires sign-up. I've thought about allowing anonymous users, but haven't implemented that yet. However, the site is free, and I'm not even doing any kind of email verification. So I won't judge you if you go with "some-fake-email@example.com" Hope your day is going well and all the best! https://auracoder.com/ June 12, 2025 at 06:01AM

We decided to launch our "course" as an MCP server. This way your coding agent actually teaches the course content to you and can help you write the code. We think this is a really interactive way to learn. Using an editor with MCP support (such as Cursor, Windsurf, or VSCode), your code agent will call the appropriate MCP tools which will return context for the agent. This context tries to instruct the agent that it should be teaching you the content, not just doing the work for you. The course is still pretty experimental and some models work better than others. Code is available in the Mastra Github repo in the mcp-docs-server package ( https://ift.tt/Dh4yZwQ... ) https://ift.tt/C8BIR17 June 11, 2025 at 12:36AM

Show HN: An open-source rhythm dungeon crawler in 16 x 9 pixels I just released my latest Godot project, a rhythm-based dungeon crawler a la Crypt of the Necrodancer. The entire game plays out in 16 x 9 pixels because of a dare from my game dev group. I've open-sourced (MIT) the code and project files. Of course, the music files I don't own aren't included in the Github project, but I'm releasing the game's hand-crafted pixel sprites under CC0. The Github page also talks about some of the tricks you need to make the rhythm part of the game play nice with the dungeon crawling part. https://ift.tt/tJQul5i June 6, 2025 at 02:20PM

Show HN: RenderDay: A GPU-only render farm for Blender https://ift.tt/hkf24Dr

Show HN: RenderDay: A GPU-only render farm for Blender Hey HN! I recently had to render my first longer Blender animation, and I found myself pretty frustrated with the existing render farms out there. Everything I tried was either buggy, overly complicated (I really don’t want to pick from a huge list of hardware options), or just *really* expensive. So, I did what anyone would do.. I built my own solution: https://renderday.com - a GPU-only render farm for Blender that’s super fast and dead simple to use. You just: 1. Upload your `.blend` file 2. Pick your settings 3. Get a price, pay, and render - done No subscriptions, no upfront costs, no contracts - just pay as you go. I pull in daily GPU prices from multiple providers (with a tiny margin to keep the lights on), so the pricing is transparent and competitive. Under the hood it's running on NVIDIA L40S GPUs (48GB RAM), with access to over 1,000 GPUs globally. Currently supports: * Blender 4.3 and 4.4 (can add more if needed) * Cycles and EEVEE * Real-time progress tracking with live preview frames * Full file encryption, auto-deletion after 30 days, no access/sharing --- But more importantly: I'd really appreciate your feedback. This started as a personal itch, but I want to build something genuinely useful for the Blender community - especially indie creators and small studios who can't afford big monthly plans or don't want to deal with complicated setup. - What do you wish render farms did better? - What features are missing for you right now? - Would you use something like this - and if not, why not? Would love to hear your thoughts - good or bad - so I can keep improving it. Thanks for reading! Sascha https://renderday.com June 10, 2025 at 12:54AM

Show HN: SelfDB – Ditch Supabase and Firebase Lock-In, Self-Host Simply https://ift.tt/puyCQat

Show HN: SelfDB – Ditch Supabase and Firebase Lock-In, Self-Host Simply Hey HN! We're a small team of developers who, like many of you, love the power and convenience of Backend-as-a-Service (BaaS) platforms. However, we've also felt the sting of vendor lock-in, wrestled with the complexities of self-hosting feature-rich open-source alternatives, and worried about unpredictable costs or the sudden disappearance of free tiers that many indie devs and small projects rely on. We believe developers deserve more control and simplicity without sacrificing functionality. After countless hours spent navigating these challenges, we decided to build the solution we wished existed. So, we built SelfDB: a self-hosted, open-source alternative to platforms like Supabase or Firebase. SelfDB provides a PostgreSQL database, secure JWT-based authentication (with anonymous access capabilities), integrated object storage, WebSocket-based real-time updates, and serverless cloud functions powered by Deno 2.0 – all packaged into a single, easy-to-deploy containerized platform. Our goal is to give you the comprehensive features you expect from a modern BaaS, but with the freedom and control that comes from truly owning your backend stack. Here’s what SelfDB offers: Full PostgreSQL Power: Your data, your schema, no compromises. Direct SQL access when you need it. Robust Authentication: Secure user management with JWT tokens and flexible anonymous access. Integrated Object Storage: A dedicated SelfDB Storage Service for your files and media. Real-time Updates: Keep your applications in sync effortlessly using WebSockets. Modern Cloud Functions: Write custom serverless logic with Deno 2.0, benefiting from its security-first approach and native TypeScript support. Dead-Simple Deployment: This is where we really focused. Forget wrestling with a dozen different containers for a self-hosted BaaS. With SelfDB, you just need to unzip , configure your .env file, and run ./start.sh. That’s it. Truly Open & Yours: Your SelfDB purchase includes full access to our source code, empowering you to redeploy the software as often as you need. While resale is not permitted, you have the freedom to modify the code to perfectly fit your requirements. Your purchase also grants you access to our exclusive customer portal. Here, you'll receive continuous, free updates and can connect with the vibrant SelfDB community to network, report bugs, and provide valuable feedback. Production-Ready: We've architected SelfDB with security, logging, and monitoring considerations from the outset, so you can build with confidence. Under the hood, SelfDB leverages a FastAPI backend, known for its high performance and developer-friendly features , ensuring a responsive API. The cloud functions run in a Deno 2.0 environment, offering a modern and secure way to extend your backend. The entire platform is containerized using Docker and Docker Compose, with persistent data managed through Docker named volumes. You can get up and running locally with just a few commands: Full details, including the architecture diagram, are in zip you get when you buy Selfdb. To celebrate our launch and thank the early adopters in the HN community, we're offering. This is a great way to try out the extended features while supporting the project. You can find more details and grab the offer at : https://selfdb.io We're incredibly excited to share SelfDB with you today! SelfDB is new, and your feedback is invaluable to us. What are your biggest BaaS pain points? What features would you love to see in a self-hosted platform like SelfDB?

Show HN: AStack – A composable framework for building AI applications https://ift.tt/xFNfRHM

Show HN: AStack – A composable framework for building AI applications AStack is a composable framework designed to simplify the development of AI applications through a "everything is a component" philosophy. It provides a zero-adaptation layer design that enables seamless integration between various AI models, tools, and custom business logic. AStack is an independent technical framework with its own architecture and ecosystem, built on top of Hlang - a highly semantic fourth-generation language (4GL) inspired by Flow-Based Programming paradigms. This foundation on Hlang, which is particularly well-suited for computational modeling and AI-generated code, is what gives AStack its power. The framework emphasizes minimalism and performance, allowing developers to create complex systems with minimal boilerplate code while maintaining complete technical autonomy. https://astack.tech https://ift.tt/VnaUIp7 June 8, 2025 at 07:21AM

Show HN: AI that extracts brand identity from websites to generate ads https://ift.tt/iqgKaoR

Show HN: AI that extracts brand identity from websites to generate ads I built this because I kept procrastinating on creating ads for my projects. The technical challenge was interesting: how do you teach AI to extract "brand identity" from a website? Turns out websites are messy. Finding the actual logo vs random images, identifying brand colors vs generic link colors, understanding brand voice from homepage copy. The solution: Custom vision models + CSS parsing + GPT-4 for voice analysis. You paste a URL, it extracts brand elements, generates platform-specific ads. Not trying to "disrupt advertising" or anything dramatic. Just solving the specific problem of "I need a Facebook ad but Canva makes me want to cry." Built with Next.js, custom image processing pipeline, OpenAI API. The brand extraction accuracy is around 85% for well-structured sites, lower for sites that are... creative with their CSS. Happy to discuss the technical approach or share code snippets if anyone's curious about the brand extraction pipeline. https://board.ad https://www.board.ad June 8, 2025 at 09:15AM

Show HN: String Flux – Simplify everyday string transformations for developers https://ift.tt/32WGAYD

Show HN: String Flux – Simplify everyday string transformations for developers I built https://stringflux.io/ to make everyday string transformations a little less painful. It’s similar to CyberChef in the sense that it supports multiple string operations, but with a cleaner, more focused UI and smart suggestions based on your input. You can also chain transformations — for example: decode base64 string which was base64 encoded from minified json → then json format (pretty-print) it — all in one flow. This is helpful when dealing with complex or nested strings, like encoded API responses or log data, where you need to apply multiple steps to make the content readable. The idea came from the frustration of jumping between different tools just to handle common string tasks. There’s a short GIF demo in the GitHub README: https://ift.tt/b7Bj2uR Would love to hear your thoughts and feedback! https://stringflux.io June 6, 2025 at 02:05AM

Show HN: Create LLM graders and run evals in JavaScript with one file https://ift.tt/5NjlOdn

Show HN: Create LLM graders and run evals in JavaScript with one file Hi HN! Run it: OPENROUTER_API_KEY="sk" npx bff-eval --demo We built a tool to help people take LLM outputs and easily grade them / eval them to know how good an assistant response is. We've built a number of LLM apps, and while we could ship decent tech demos, we were disappointed with how they'd perform over time. We worked with a few companies who had the same problem, and found out scientifically building prompts and evals is far from a solved problem... writing these things feels more like directing a play than coding. Inspired by Anthropic's constitutional ai concepts, and amazing software like DSPy, we're setting out to make fine tuning prompts, not models, the default approach to improving quality using actual metrics and structured debugging techniques. Our approach is pretty simple: you feed it a JSONL file with inputs and outputs, pick the models you want to test against (via OpenRouter), and then use an LLM-as-grader file in JS that figures out how well your outputs match the original queries. If you're starting from scratch, we've found TDD is a great approach to prompt creation... start by asking an LLM to generate synthetic data, then you be the first judge creating scores, then create a grader and continue to refine it till its scores match your ground truth scores. If you’re building LLM apps and care about reliability, I hope this will be useful! Would love any feedback. The team and I are lurking here all day and happy to chat. Or hit me up directly on Whatsapp: +1 (646) 670-1291 We have a lot bigger plans long-term, but we wanted to start with this simple (and hopefully useful!) tool.

Show HN: Smart Palette – Reimagining AI Art https://ift.tt/G6JlmW4

Show HN: Smart Palette – Reimagining AI Art Hi HN, I'm Nick. Over the last 6 months I’ve been building Smart Palette – a platform to help anyone create unique, wall-ready art without needing to be a prompt expert. I started this because I wanted to unleash creativity in anyone and help them bring their art ideas onto their wall through a simple, guided and inspiring process. Instead of figuring out the “right” words to use, you just select your interior design style, room, art style, theme, and color palette. You can simply describe what you want to see and add your desired colors — or let Smart Palette handle it for you. Smart Palette uses a streamlined UI that my backend then translates into optimized, detailed prompts. A lot of the work went into this "translation" layer to ensure optimal model selection, settings and generation techniques depending on the user’s creative context. It also has a full print-on-demand (UHD) integration including various cusotmization options and an art preview feature. This is an early version, and I'd be very grateful for any feedback you have on the concept, the UX, or any technical aspects. Happy to answer any questions! You can try it out with a free trial and generate your first artwork. Here’s a quick walkthrough: https://ift.tt/QwyTfP7?... https://ift.tt/dpViZq3 June 4, 2025 at 11:28PM

Show HN: Page Magic: Use AI to customize any web page I built this Chrome extension (using Claude Code) to help me customize the style of web pages to my liking. It's not perfect, but it does a decent job most of the time. You will need to bring your own Anthropic API key and add it in the settings if you want to try it out. Features: - Use natural language to customize any web page - You can make the changes apply to the current page only or domain-wide - You can see your prompt history for the page and toggle any of them - Cost is tracked using Anthropic pricing and token counts (it may not be 100% accurate, but close enough) Cost per change tends to be around $0.005 depending on page size. Things you can try: - Change the background color, text color, etc. - Remove obnoxiously large hero images - Reduce line spacing - Increase content area width - Remove stickiness of top headers - ... anything you can think up https://ift.tt/IXGxuiK June 3, 2025 at 04:24AM

Show HN: I build one absurd web project every month I’ve been building absurd, mostly useless web projects for fun — and I publish one every month at absurd.website. These are deliberately non-functional, weird, sometimes funny, sometimes philosophical — and usually totally unnecessary. Some examples: Sexy Math — solve math problems to reveal erotic images. Trip to Mars — a real-time simulation that takes 7 months to finish. Add Luck to Your e-Store — add a waving cat widget to boost your conversion via superstition. Microtasks for Meatbags — the future: AI gives prompts, humans execute. Invisible Lingerie — it’s sexy. And invisible. Artist Death Tracker — art prices spike when artists die. We track that. Open Celebrity — one open-source face, shared by all. Together we make her famous. I just enjoy exploring what the web can be when it doesn’t try to be “useful”. Would love to hear what you think — and absurd ideas are always welcome. https://absurd.website June 2, 2025 at 11:52PM

Show HN: GoogLLM – Google search that returns Markdown instead of HTML https://ift.tt/DiYRdp0

Show HN: GoogLLM – Google search that returns Markdown instead of HTML As part of my bigger goal to make the web more agent-friendly, this weekend i decided to tackle google. The "AI-native" search APIs like Tavily and Exa exist, but they require setup and don't actually use Google's results. So I built something simple - a proxy that takes Google search URLs and returns the results as clean markdown instead of HTML. You literally just change "google.com" to "googllm.com" in any search URL. ```bash # Returns 500KB of HTML: curl " https://ift.tt/LUFtbH4 " # Returns clean markdown: curl " https://ift.tt/rNu7s5z " ``` *What it does:* - Serves normal HTML to browsers (so humans can use it normally) - Returns markdown to everything else (curl, fetch, LLM agents) - Supports all Google search types: web, images, news, scholar, shopping, etc. - No auth needed for testing (10 requests/hour free) *Technical approach:* - Content negotiation based on Accept headers - Caches results to avoid hammering Google - Simple pricing: 0.5¢ per search after free tier I built this over a long weekend because I was tired of writing HTML parsers for every project. The whole thing is designed around a single principle: make Google search results consumable by LLMs without any complexity. *Questions for HN:* - Is this approach too simplistic? Should search APIs be more complex? - How do you currently handle search in your LLM applications? - Any concerns about the proxy approach vs. building from scratch? The llms.txt documentation is intentionally comprehensive (2500 tokens) so any LLM can understand and use it immediately. Live demo: https://googllm.com API docs: https://ift.tt/1enudfl Would love feedback on the approach and any edge cases I might have missed. https://googllm.com June 2, 2025 at 11:07PM
