Every key and OAuth token carries full organisation authority, with no read-only or scoped credential, and no request rate limits are documented.\n\n## Before you call either\n\n### Browserbase\n\n1. Use x402.browserbase.com when you have a wallet and no key. Terminate the session to get unused minutes refunded\n2. Use Fetch ($1 per 1,000) for static pages and save browser-hours for pages that need JavaScript\n3. Close sessions explicitly. Each session bills at least one minute, and idle ones keep billing\n4. Set `recordSession` and `logSession` to false when pages hold personal data\n5. On 429, wait `retry-after` seconds before creating another session\n\n### Skyvern\n\n1. Connect to https://api.skyvern.com/mcp/x/lean or /x/operate, or send `X-Skyvern-Scope`, so the client loads 32 or 29 tools. The scope filters the list and does not limit permissions\n2. Use a separate Skyvern organisation for each blast radius. Any key or OAuth token can read and write stored credentials and delete workflows\n3. Never pass passwords to `skyvern_act` or `skyvern_type`. Store them as credentials and call `skyvern_login`\n4. Set `max_steps` on tasks, or `x-max-steps-override` on agent runs, to cap credits. A run that reaches the cap ends as `timed_out`\n5. On 503 from POST /v1/run/agents, wait `Retry-After` seconds. No run was created, so resubmitting is safe\n\n## Questions\n\n### Which is better for AI agents, Browserbase or Skyvern?\n\nBrowserbase scores 76.2 (BB) on agent readiness against Skyvern's 63.1 (B), and leads in 3 of 7 scored categories. Skyvern leads on schema \u0026 documentation and security \u0026 auth.\n\n### Do Browserbase and Skyvern need an API key?\n\nBrowserbase needs an API key. Skyvern takes an API key or an OAuth sign-in. An agent can also pay Browserbase per call over x402, with no account.\n\n### Can an agent call Browserbase and Skyvern without installing anything?\n\nYes. Browserbase has a hosted endpoint at https://api.browserbase.com/v1 and Skyvern at https://api.skyvern.com/v1.\n\n### Are Browserbase and Skyvern open source?\n\nNo open-source release is listed for Browserbase. Skyvern is open source (AGPL-3.0 for the open-source server, SDKs and MCP server. Skyvern Cloud is a proprietary service under Skyvern's terms, and its anti-bot measures aren't in the repository).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/browserbase-vs-skyvern.json, and with the fewest tokens: https://www.anchorterminal.com/compare/browserbase-vs-skyvern.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"browserbase\", \"b\": \"skyvern\"}`.
