Thanks! Yeah Claude Code’s native browser is getting better. ProofShot is agent-agnostic though — works with Cursor, Codex, any agent that can run shell commands. And the proof bundle you get at the end (viewer.html with video + timeline +

yep adding soon, agree it is the most recurring question

Thanks! Web only for now, runs headless Chromium. Desktop is the #1 request, likely through accessibility APIs or OS-level screenshots. On the roadmap.

Web only for now since it runs headless Chromium. For Flutter web builds it’d work, but native Flutter apps would need emulator integration which is on the roadmap. Feel free to open an issue on the repo.

Fair point, clearly the first question everyone has. Will add a comparison section to the README.

ProofShot isn’t a Playwright alternative, it’s built on agent-browser (from Vercel Labs), which is a different runtime. The value isn’t “can control a browser” — playwright does that fine, and in fact agent-browser is built on top of Playwr

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 would need accessibility APIs or OS-level screenshot capture. It’

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 script the login as part of your proofshot exec steps (type ema

interesting, which model were you using for the vision part? In my experience Claude Sonnet and Opus handle UI screenshots reasonably well, not perfect but good enough that the agent can catch obvious layout issues and iterate. Definitely n

agent-browser runs locally (it’s a Rust CLI + Node daemon on your machine), so there’s no cloud dependency on Vercel, it’s just built by the Vercel Labs team. Everything stays local :)

Simon’s tools are really great. Showboat is more for static screenshots though. ProofShot is the full session: recording, error capture, action timeline, PR upload. Different scope i'd say.

by jberthom 6mo ago
The agent drives interactions through proofshot exec — clicks, typing, navigation and each action gets logged with timestamps synced to the video. So in the viewer you can scrub through and click on action markers to jump to specific moment

ah feel your pain.. Codex interaction is exactly the pain point. “I fixed it” / “no you didn’t” five times in a row, you feel gaslighted by your own agent in a way. That’s the loop I wanted to kill. I didnt' know about Mozilla scr

Thanks! Yeah the before/after PR thing is exactly what proofshot pr is built for.

by jberthom 6mo ago
DevTools MCP is great for live debugging in the moment. ProofShot is more about generating a proof bundle after the fact, something you can review on a PR without having been there when the agent ran. Different use cases I think.

by jberthom 6mo ago
yes as saintfire said :) ProofShot is just a CLI, not tied to any IDE. If you’re in Antigravity or VSCode and their built-in preview works for you, great. This is for people using Claude Code, Codex, or any terminal-based agent where there’

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, but for mobile the a11y approach could be way more efficient. Wo

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 emulator. For native desktop, probably accessibility APIs or OS-l

Yes agent-video is focused on high quality recording. ProofShot uses agent-browser’s recording under the hood but the value is really in everything else: error collection, server log capture, the interactive viewer with synced timeline, and

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 your server logs, collects console errors with pattern matching

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 browser and begin recording, exec to interact with the page, stop to

Yes exactly. I'm actively maintaining it so if you miss anything just drop an issue on Github and I'll look into it

This is the first time I hear of this case as I think few people create distinct applications. We use Auth0 for authentication and we'll check with them as it seems the issue is on their side. I'll let you know when we've fig

Yes we didn't dedicate efforts to integrating an ad blocker because we mostly integrate applications in which you shouldn't see ads but Twitter or Instagram are good examples of where it's needed. We are working hard to integ

Franz is all about handling messaging app while we handle all types of web applications. As for Rambox, indeed they are closer to what we do with a different type of interface though. We do support self-hosted apps (any kind of custom apps)

Thanks for the feedback. We plan on insisting on the "Free" aspect on the V.2 of our website so it's clear that it is free for the individual user. Once we price for teams we'll have a dedicated page.

Thanks for your feedbacks! On some of your points: - we do allow you to use multiple Gmail accounts, back when you used it it might not have been obvious enough but you can use as many Google accounts as you'd like - indeed we are work
