Show HN: I built a Web-Scraper API that is 6-7x more efficient than current ones Runo is a web-scraping API that returns typed, structured JSON. You define a schema (field name, type, example value), and Runo fetches the page and returns the data. No HTML, no parsers, no post-processing. Over the past few weeks, I have been building this non stop. Currently, every scraper API out there solves the site fetching problem but left the extraction of the actual data entirely to users. Runo makes that completely disappear. For Runo, I went ahead and added JS rendering, stealth mode, and full LLM extraction to make this a fully functional and capable of scraping most if not all sites. Also, another major problem with current web scrapers is that they charge per feature or bundle them into expensive credit tiers. A single large or JS rendered request can cost 5-75 credits, which means you essentially get nothing out of their plans. Runo is flat per request, no matter the site. At the Scale tier, Runo works out to $0.90 per 1,000 effective requests vs. around $6 for the nearest Firecrawl equivalent. My jaw dropped when I was testing Runo and came across these numbers. I created a free tier that is 500 requests/month, no credit card required. Take it for a spin and let me what can be improved. I would love feedback. https://ift.tt/jw05AQz May 15, 2026 at 01:02AM

Show HN: Rotunda - A browser built for agents with simulated typing https://ift.tt/6iwW5ML

Show HN: Rotunda - A browser built for agents with simulated typing Hi HN! Pierce here. Rotunda is a firefox fork primarily intended for agent use, which I’ve been hacking on nights/weekends. There was a [lengthy]( https://ift.tt/FYliVX6 ) discussion last week on how expensive computer use models are. The cost is going to drop eventually, but I think on some level it's still usually the wrong primitive. The web gives us access to beautiful structured formats, plaintext, etc... why throw that away if we don't have to? I realized at some point that for 99% of automations I just want agents to be able to control my Chrome instance. But that’s easier said that done: CDP (the Chrome automation protocol) leaks a ton of state about being programmatically controlled, either by toggling window attributes or by running `page.evaluate()` commands right in the page context. Plus if you look at an automation running it's pretty obvious what happens: the mouse jumps around, fields are filled instantly, etc. Rotunda tries to fix this. Its standout features: - Realistic simulation of mouse movements and keyboard commands, powered by a trained RNN on my own timing patterns from the last week. (still feel weird about opting-in to a key logger but whatever) - Doesn’t lie about its host specs, only fibs about some client side details. Stealth browsers are too easy to flag statistically when you’re adding noise to canvas pixels or audio pipelines. - It runs on your local device with a CLI or Playwright API accessible to Claude, Codex, or whatever your harness-de-jure today looks like. - Patches modern Firefox (150) with an agentic harness to keep this updated over time MPL-2.0 on GitHub: https://ift.tt/f43TChv Longer writeup on the design choices: https://ift.tt/D6g1yPi Also check out the demo on the site! https://www.rotunda.sh/ Pretty excited by how this turned out but we’re still super early. Give it a try and please flag any issues! https://ift.tt/f43TChv May 13, 2026 at 05:44PM

Show HN: I spent $100 in Claude tokens and 1k battles training my AI tank Hi HN, I built AgenTank. It is a small game where an AI agent writes the logic for your tank. You watch it fight, give strategic feedback, let the agent update the tank code, and send it back into battle. I have run 1,000+ battles on my own tank and spent about $200 in Claude credits improving it. The part I enjoy most is not just winning, but watching the tank make visible mistakes, thinking of a better strategy, and seeing whether Claude can turn that into better code. https://ift.tt/pTao2cI May 13, 2026 at 06:20AM
