Agent Browser
I add Agent Browser so Claude Code can navigate, click, and screenshot the app it just shipped, turning code-gen into end-to-end QA in one harness. Lets Claude Code navigate, take screenshots, and click for you.
Strengths
- Official Vercel Labs skill, aligned with agent QA best practices
- Closed-loop: Claude generates code then verifies it actually works in a real browser
- Automatic screenshots, visual proof rather than textual assertions
- Open source, Apache-style, auditable and forkable
Limitations
- Tokens burned per browser action, context fills fast on a long QA session
- DOM-bound, no pixel-perfect visual diff without extra tooling
Best for
- Vibecoders verifying their sites/apps after each code-gen pass
- Agentic QA: let Claude run user journeys on your behalf
- Dogfooding frontend features where visual rendering must be confirmed
