The privacy policy says inputs are used to train Browser Use's models, API keys have no documented scopes, and no prompt-injection guidance was found in the docs.\n\n**Chrome DevTools MCP.** Performance traces, network inspection, heap snapshots and Lighthouse audits in one server. Usage statistics go to Google by default until you pass `--no-usage-statistics`.\n\n## Before you call either\n\n### Browser Use\n\n1. Send the key as `X-Browser-Use-API-Key` with no Bearer prefix. A Bearer header returns 401\n2. Stop browsers with `PATCH /api/v4/browsers/{id}` and `{\"action\":\"stop\"}`. Closing CDP or the SDK client leaves the browser billing\n3. Poll `GET /runs/{id}/status`, not the full run, and wait for the returned Retry-After on 429, which can be 300 seconds at the edge\n4. Before resubmitting after a timeout, read the existing run's status. The server keeps running and may already have submitted a form\n5. With a wallet and no key, call x402.api.browser-use.com on `/api/v2` or `/api/v3` routes. A task stops with INSUFFICIENT_CREDITS if credit runs out mid-run\n\n### Chrome DevTools MCP\n\n1. Pass `pageId` on every page tool. Call `list_pages` first to get it\n2. Start with `--slim` for plain browsing, or turn off categories you don't need\n3. Run with `--isolated` for untrusted sites. The default profile persists between runs\n4. Use `filePath` on large outputs such as traces and snapshots to keep them out of context\n5. Add `--no-usage-statistics` if the operator hasn't agreed to Google telemetry\n\n## Questions\n\n### Which is better for AI agents, Browser Use or Chrome DevTools MCP?\n\nBrowser Use and Chrome DevTools MCP score within a point of each other on agent readiness, 77.9 (BB) and 77 (BB). Chrome DevTools MCP leads on agent ergonomics, maintenance \u0026 community and transparency \u0026 trust.\n\n### Do Browser Use and Chrome DevTools MCP need an API key?\n\nBrowser Use needs an API key. Chrome DevTools MCP needs no key. An agent can also pay Browser Use per call over x402, with no account.\n\n### Can an agent call Browser Use and Chrome DevTools MCP without installing anything?\n\nBrowser Use has a hosted endpoint at https://api.browser-use.com/api/v4. Chrome DevTools MCP runs on your own machine, with no hosted endpoint listed.\n\n### Are Browser Use and Chrome DevTools MCP open source?\n\nYes. Browser Use is open source (MIT for the open-source library and the SDK. Browser Use Cloud is a proprietary service under Browser Use's terms of service). Chrome DevTools MCP is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/browser-use-vs-chrome-devtools-mcp.json, and with the fewest tokens: https://www.anchorterminal.com/compare/browser-use-vs-chrome-devtools-mcp.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"browser-use\", \"b\": \"chrome-devtools-mcp\"}`.
