No service agreement is published, only a website terms of use, and the documented CDP connection puts the API key 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### Anchor Browser\n\n1. Send the key in the `anchor-api-key` header. For CDP, build `wss://connect.anchorbrowser.io?apiKey=\u003ckey\u003e\u0026sessionId=\u003cid\u003e` and keep that URL out of logs\n2. Set `session.timeout.idle_timeout` and `max_duration` and end sessions with DELETE. The default maximum is 180 minutes, and browser time bills by the minute\n3. Session creation is capped at 5 a minute on Free, 25 on Starter and 100 on Growth. On 429, wait for the `Retry-After` seconds\n4. Connect the `Anchor` MCP server or `Anchor (all)`, not both, because the docs say the pair duplicates tool names\n5. Authenticated browsers, CAPTCHA solving and proxies by country need the Starter plan or higher. The Free plan and Agent Access keys run plain sessions and web tasks\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, Anchor Browser or Puppeteer?\n\nPuppeteer scores 70.6 (BB) on agent readiness against Anchor Browser's 67.3 (B), and leads in 3 of 7 scored categories. Anchor Browser leads on agent ergonomics.\n\n### Can an agent call Anchor Browser and Puppeteer without installing anything?\n\nAnchor Browser has a hosted endpoint at https://api.anchorbrowser.io. No hosted endpoint is listed for Puppeteer.\n\n### Are Anchor Browser and Puppeteer open source?\n\nNo open-source release is listed for Anchor Browser. Puppeteer is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/anchor-browser-vs-puppeteer.json, and with the fewest tokens: https://www.anchorterminal.com/compare/anchor-browser-vs-puppeteer.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"anchor-browser\", \"b\": \"puppeteer\"}`.
