ProofShot

I've always found screenshots on PRs incredibly helpful as a reviewer. Historically I've had mixed success getting my team to consistently add screenshots to PRs, so this tool…

I'm going the opposite of everyone else is saying. This is sick OP based on what's in the document, it looks really useful when you need to quickly fix something and need to…

This is exactly the missing feedback loop for AI coding agents simple, practical, and surprisingly powerful.

What does this do that playwright-cli doesn't? https://github.com/microsoft/playwright-cli

I think playwright doesnt capture video, right?

> With Playwright the agent needs to write a test script, run it, collect screenshots, parse output separately… it’s a lot of glue code. Uh what are you talking about? It most…

Yes it does. https://github.com/microsoft/playwright-cli?tab=readme-ov-file#devtools I'm pretty sure OP wrote their own version of playwright because they didn't know this existed.

Looks nice! Does it work for desktop applications as well, or is this only web dev?

How would this play with mobile apps? I'd love to see an agent doing work, then launching app on iOS sim or Android emu to visually "use" the app to inspect whether things work…

This is awesome, does it work with desktop application ?

VSCode and Antigravity already do this. What am I missing?

Gemini on Antigravity is already doing this.

Not to pile on, but I was using Claude Code through the native application and it started doing exactly this on its own, side by side with my prompt, running the server and…

Yes agree. Web only for now since it runs on headless Chromium. Desktop and mobile are the #1 request though. For mobile the path would be driving an iOS Simulator or Android…

Web only for now. It runs headless Chromium under the hood. Desktop and mobile are the #1 request. Mobile path would be iOS Simulator or Android emulator integration. Desktop…

Yes for now focused on web but accessibility tree dumps seems like a good alternative to screenshots for native apps. For web, agent-browser already uses compact element refs,…

Hey jberthom, this is awesome! How do you handle logged in sessions/user authentication? I built something much much more primitive, but I have it actually storing session data…

Right now agent-browser launches a fresh Chromium instance each time, so no persisted auth. For apps behind login, you’d need to either hit a page that doesn’t require auth, or…

Maker here. Playwright is great, I use it too. The difference is really about who’s driving. ProofShot is meant for agents that just need shell commands, start to open the…

How does this compare to raw https://github.com/vercel-labs/agent-browser ?

ProofShot sits on top of agent-browser. agent-browser gives you the browser primitives (click, navigate, screenshot). ProofShot adds the session stuff: starts recording, pipes…

It looks similar to agent-video, which is also based on agent-browser: https://www.mux.com/blog/agentic-video-screen-recording I don't think you need either, though, because…

I find the official Chrome DevTools MCP excellent for this. Lighter than Playwright, the loop is shorter, and easy to jam into Electron too.

Claude Code with --chrome is excellent at building UIs (and hopeless without it!)

I use the Claude Chrome extension for this. Works wonderfully. It lets Claude click through features itself, etc.

seems similar to a couple of simonw's recent tools? https://simonwillison.net/2026/Feb/10/showboat-and-rodney/
