Chrome MCP usually means Claude's Chrome extension driving your real, logged-in browser. Playwright MCP drives a clean one. Here is when each wins, and why.
agent-browser vs Playwright CLI: both give coding agents a token-lean browser. How Vercel's Rust CLI and Microsoft's compare, with real commands and a clear pick.
Test file downloads on Test-Lab. When an AI run or Playwright script downloads a PDF, CSV, or image, the file shows up in the run report so you can open it and check it was right.
Test-Lab now repairs flaky and newly-failing Playwright tests automatically: AI diffs a failing run against a passing one, rewrites the saved test, and verifies it passes before applying it. Cut test maintenance and the cost of a brittle E2E suite. Now in beta on the Scale plan.
Upload your own files to Test-Lab and reference them in any test with {{file.custom.resume}}. Test uploads with the exact PDF, CSV, image, or document your app expects, in AI runs, Playwright scripts, and pipelines.
test-lab now records every change to your account in one activity log: who made it, which surface it came from, and the exact before and after. Credentials stay masked.
Test-Lab's runners live on the public internet, so out of the box they cannot reach localhost, staging behind SSO, or VPN-only URLs. The Tunnel extension routes a single run through your own browser, so the test reaches anything your machine can.
