Show HN: Endo – A Higher-Order Harness https://ift.tt/dQSNrow

Show HN: Endo – A Higher-Order Harness Endo is a Higher-Order Harness (HOH). From the easiest concept to understand to the more complex ones, Endo gives you: * A single, simple UI to use any agent provider with your existing subscriptions, and hot-swap agents right in the middle of a session. * An orchestration layer, which I call HOH, allowing arbitrary composition of agents to achieve any workflow. A fun case I tried was asking Fable and Astra to mock a presidential debate. * An agent protocol that abstracts any agent. The key insight here is that every LLM is an agent—instead of treating the LLM as just one node inside an external ReAct loop. Endo was a concept formed while I was building OpenChart ( https://ift.tt/48P2CE3 ). To power trading workflows, I needed to support scenarios where strict determinism is required, while still keeping the flexibility of an agent's inference-time decision-making capability. A new form factor was needed between rigid n8n-style workflows and open-ended ReAct loop agents. Thus the creation of Endo. Endo is short for Endomorphism, a term rooted in category theory and functional programming. An endomorphism is a function that transforms an object into another object of the same type. Similarly, Endo itself is built purely on functional programming principles, relying heavily on Effect ( https://ift.tt/SN7n3vA ). ..And if you have patience to speak technical jargons, Endo is: * An agent orchestration layer—Higher-Order Harness (HOH)—where an entire agent is treated the same as a single LLM call, enabling arbitrary composition of extremely complex workflows. * A way to abstract any harness into a standardized protocol, where raw models and agents behave the exact same way, in a KV-cache-friendly manner. * A workflow engine that enables arbitrary composition of agents with a single workflow language. It's completely open source, and if you think this idea is cool, let's build together. Just for the fun of it. https://ift.tt/KtVIg4H October 16, 2026 at 01:32AM

Show HN: Forwarder.cc – Static-site forms sent to your inbox, pay per message https://ift.tt/xYp1u34

Show HN: Forwarder.cc – Static-site forms sent to your inbox, pay per message TL;DR: 12 years ago I built a service that forwards simple HTML forms to an email address. I've been procrastinating on finishing it ever since, until today. You point your form at it and every submission lands in your inbox. It runs on credits, 1 credit = 1 message, no subscription. Perfect for static websites. — Hey folks, back around 2014, alongside my job as a software engineer, I was building a lot of static websites for my own clients, mostly small businesses that just wanted a simple site. To avoid headaches, I went fully static, often hosted on GitHub Pages and similar. But most clients also wanted a contact form, and a form needs a server running somewhere. I had my own weekend-hacked service for this, which literally just forwarded the form to the client's email. I didn't invent anything here: one service I particularly remember was FormKeep by thoughtbot, that I really liked. So I started building my own, mostly because I loved losing myself in side projects like this, and also because I was a cheap ass and thought I could do something similar for less, and without a subscription. By 2016 I had done about 90% of what I'm showing you today. I called it "The Great Forwarder". Everything was ready: backend, frontend, hosting, Stripe, landing page. I even had a designer friend help with the design (sorry, Valentin, if I've botched it since). Then I started another project, which took off right away and took all my attention for a while. Fun fact: that project has been using this service ever since, and almost every message ever sent through it came from there. So for years, I kept Forwarder.cc up to date, upgrading libraries and trying new ones: axios, got, Redux, Zustand, create-react-app, webpack, Vite… It became my laboratory for everything I wanted to explore, while always staying up and maintained (again, for my own use only). The only thing that ever held me back from launching it was a missing help center, and, more honestly, the fear of putting it in front of people. So today's the day: after 12 years of procrastination, I finally finished the help center. I know there are a ton of similar services nowadays, but anyway, what do you think of that help center? https://forwarder.cc October 15, 2026 at 10:47PM

Show HN: GitVolt, open source fast Git GUI (Tauri/CEF) https://ift.tt/tiqspNg

Show HN: GitVolt, open source fast Git GUI (Tauri/CEF) Hi HN! I've been working on this for the past few weeks. I've been using GitKraken for a whole 10 years now, and I've always loved it, but lately I've found it to be a bottleneck, and I haven't seen it improve the features I really care about. So, as many others have done recently, I took a shot at using Opus 5.5 to help me build my dream Git GUI app. I did take massive inspiration from GitKraken (the look and feel is a close match since it's what I feel comfortable with) but everything is built from scratch. I made lots of different UX choices that I think help streamline things. Most importantly, performance was the key thing to get right at the start. I daily-drive Linux so that was first. I went with Tauri to have a really fast Rust core, and after doing performance testing with WebKitGTK it wasn't good enough. So I'm using Tauri's v3 alpha with CEF (Chromium) which made it easy to get a butter smooth 60fps for scrolling a huge list of commits (whereas I would barely get 10fps in my large repo with GitKraken, with tons of hitching). Everything feels so much faster. The website is best viewed on desktop, I included a fully functional web-only version of the app (mocked git and gitlab) so you can try it out! Some cost numbers: ~16 billion tokens, ~$5.4k at API rates, 5.2 full weekly quotas (spread over two 5x plans), ~$120 of subsidized plan cost. https://gitvolt.com/ October 15, 2026 at 04:25AM

Show HN: I think Apple should have built this a long time ago https://ift.tt/lYoMhyt

Show HN: I think Apple should have built this a long time ago Built this little tool a while ago and shared it with a few friends. The feedback I got was great that I decided to release it publicly. It's not just another 'clipboard'... Honestly, would love you guys to try it out! This is my first public release of a product with a price tag! I have 0 expectations for it... but I genuinely love using it myself. https://ift.tt/Bm8aA2j October 15, 2026 at 04:18AM
