What it does

Deploy AI agents that flow through your production app like a real user. Just provide a URL and get notified when something breaks.

Test In Production

Deploy AI agents that flow through your production app like a real user. Just provide a URL and get notified when something breaks. Full-stack rendering has infinite moving parts. When backend meets the browser, things break in weird ways that only a real user would see. Precision-guided agents for critical paths. Describe your goal in simple english, like "Add a $20 bag to cart and checkout," and the agent handles the rest. Autonomous discovery. Just provide the URL, and our agents roam your application like a curious user, clicking, scrolling, and uncovering hidden edge cases. We instantiate a fleet of headless browsers. No SDKs. No code changes. We enter your environment exactly as a…from papercuts.dev

  Hi HN, We just launched Blocks - an AI platform where anyone can build custom work apps and AI agents in minutes, no coding required. We’re seeing a shift in how software is built and used. With AI, software isn’t just about tracking processes anymore - it can actively help people get work done. The problem is that most teams still face 2 options: either buy off-the-shelf tools that never quite fit, or invest a lot of time and money into custom development. Neither works well. Blocks is the third option. It’s an AI-native platform where teams can create apps and AI agents for their workflows…

  ProofShot – Give AI coding agents eyes to verify the UI they buildMar 2026 · github.com · ▲161

  I use AI agents to build UI features daily. The thing that kept annoying me: the agent writes code but never sees what it actually looks like in the browser. It can’t tell if the layout is broken or if the console is throwing errors. So I built a CLI that lets the agent open a browser, interact with the page, record what happens, and collect any errors. Then it bundles everything — video, screenshots, logs — into a self-contained HTML file I can review in seconds. proofshot start --run "npm run dev" --port 3000 # agent navigates, clicks, takes screenshots proofshot stop It works with…

  As a founder, I've always had the hardest time building landing pages. You either buy a template and spend hours editing, or scream at Cursor to "make it beautiful". It's exhausting and waste of our time as founders. We simply need AI to generate beautiful landing pages that we can ship. I'd been working on this problem statement for a while and was able to get great results when I provided AI with a detailed design system to follow. So I ended up building a collection where I've curated 100s of design systems for AI tools to use. Now, after launch of Nano-Banana, I updated our flow to first…

  An AI agent that learns your product and guides your users2025 · frigade.ai · ▲69

  Hey HN! My name is Christian, and I’m the co-founder of https://frigade.ai. We’ve built an AI agent that automatically learns how to use any web-based product, and in turn guides users directly in the UI, automatically generates documentation, and even takes actions on a user’s behalf. Think of it as Clippy from the old MS Office. But on steroids. And actually helpful. You can see the agent and tool-calling SDK in action here: https://www.youtube.com/watch?v=UPe0t3A1Vpg How is this different from other AI customer support products? Most AI "copilots" are really just…

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
