The API token travels in the URL query string by default, cloud tokens carry no scopes, and no machine payment route exists.\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### Browserless\n\n1. Send the token as `Authorization: Bearer` to the MCP server. On REST and WebSocket routes it goes in `?token=`, so keep those URLs out of logs\n2. Close sessions as soon as the work is done. Browser time bills one unit per 30 seconds, rounded up, idle or not\n3. For multi-step work with `browserless_agent`, set `keepSessionAlive: true` on the first call and pass the returned `sessionId` after that. Sessions are one-shot by default since server 1.33.0\n4. On 429, back off and retry. It means the plan's concurrency limit or queue is full, usually from sessions left open\n5. Match the path to the protocol. Use `/chromium` for CDP clients and `/chromium/playwright` only for `playwright.connect()`\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, Browserless or Chrome DevTools MCP?\n\nChrome DevTools MCP scores 77 (BB) on agent readiness against Browserless's 70.4 (BB), and leads in 6 of 7 scored categories.\n\n### Do Browserless and Chrome DevTools MCP need an API key?\n\nBrowserless takes an API key or an OAuth sign-in. Chrome DevTools MCP needs no key.\n\n### Can an agent call Browserless and Chrome DevTools MCP without installing anything?\n\nBrowserless has a hosted endpoint at https://production-sfo.browserless.io. Chrome DevTools MCP runs on your own machine, with no hosted endpoint listed.\n\n### Are Browserless and Chrome DevTools MCP open source?\n\nNo open-source release is listed for Browserless. 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/browserless-vs-chrome-devtools-mcp.json, and with the fewest tokens: https://www.anchorterminal.com/compare/browserless-vs-chrome-devtools-mcp.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"browserless\", \"b\": \"chrome-devtools-mcp\"}`.
