The hosted MCP setup page passes the API key as `?browserbaseApiKey=` in the URL.\n\n**Puppeteer.** Puppeteer is a stable, Apache-2.0 library on 25.13.0, with ten releases since 27 July 2026, typed APIs, locators that wait and retry, and accessibility snapshots an agent can read. It has no MCP server or llms.txt of its own, and 10 of the 20 most recent CI runs on main failed between 7 and 13 October 2026.\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 ($1 per 1,000) for static pages and save browser-hours for pages that need JavaScript\n3. Close sessions explicitly. Each session bills at least one minute, and idle ones keep billing\n4. Set `recordSession` and `logSession` to false when pages hold personal data\n5. On 429, wait `retry-after` seconds before creating another session\n\n### Puppeteer\n\n1. Install with `npm i puppeteer`, which downloads a matching Chrome for Testing. Use `puppeteer-core` to bring your own browser\n2. Prefer `page.locator()` over `page.$()`. Locators wait for the element to be visible and stable before acting\n3. Read pages with `page.accessibility.snapshot({interestingOnly: true})` rather than full HTML to keep output short\n4. Catch `TimeoutError` separately from `TargetCloseError`. The first can be retried, the second needs a new page or browser\n5. Packages are ESM only since 25.0.0. Use `import puppeteer from 'puppeteer'` rather than `require`\n\n## Questions\n\n### Which is better for AI agents, Browserbase or Puppeteer?\n\nBrowserbase scores 76.2 (BB) on agent readiness against Puppeteer's 70.6 (BB), and leads in 5 of 7 scored categories. Puppeteer leads on security \u0026 auth.\n\n### Can an agent call Browserbase and Puppeteer without installing anything?\n\nBrowserbase has a hosted endpoint at https://api.browserbase.com/v1. No hosted endpoint is listed for Puppeteer.\n\n### Are Browserbase and Puppeteer open source?\n\nNo open-source release is listed for Browserbase. Puppeteer is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/browserbase-vs-puppeteer.json, and with the fewest tokens: https://www.anchorterminal.com/compare/browserbase-vs-puppeteer.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"browserbase\", \"b\": \"puppeteer\"}`.
