Iris

What it does

Iris gives your AI coding agent eyes into your running web app. Verify API calls, DOM changes, console errors, and routes with deterministic assertions instead of screenshots. Open source, MCP-based, ~73× fewer tokens than full-page snapshots.

Iris gives your AI coding agent eyes into your running web app. Verify API calls, DOM changes, console errors, and routes with deterministic assertions instead of screenshots. Open source, MCP-based, ~69× fewer tokens than full-page snapshots.

Iris gives your coding agent eyes inside your running app . Every change verified with evidence. No screenshots. The agent can’t check its own work. Screenshots are expensive and blind. So you click through the same flows, after every edit. Your app already knows everything that happened. Iris exposes it to your agent over MCP, as evidence instead of pixels. The page looks fine. The POST returned 500. Iris reports method, URL, status, and timing. Baseline now, diff later. Iris tells you what silently went missing. Store commits, websockets, async jobs. One iris.signal() call surfaces them. Including the assertion teams forget: “no errors at all during this flow.” Clicks that do nothing.…from syrin.ai

  VibeShift MCP2025 · github.com · ▲141

  Hi HN, We are the devs behind VibeShift. We have been building this MCP server to put AI coding assistants in an automatic feedback loop. They code, test, debug, fix everything until we have a fully working, secure code. It tests like a real user, copies network/console and logical errors to give them back to cursor. (1 min demo - https://www.youtube.com/watch?v=bN_RgQGa8B0) We felt this was the natural next step for AI coding assistants. And with new asynchronous assistants like codex, having a plug & play tester makes sure you don't have to spend time debugging and…

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Performative-UI – A react component library of design tropes▲1,181

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
