Which one, for what

Browserbase BB

Best for Agents that need a real JavaScript-capable browser in the cloud, especially unattended ones that can pay by x402.

Ahead on

  • Reliability, 90 against 80
  • Agent ergonomics, 75 against 67
  • Payments & pricing, 90 against 60

Also in its favour

  • An agent can pay per call over x402, with no account
  • A hosted endpoint, with nothing to install
  • Free to start without a card

Watch for

The hosted MCP setup page passes the API key as ?browserbaseApiKey= in the URL

Puppeteer BB

Best for Agents that write and run Node.js scripts against Chrome or Firefox.

Ahead on

  • Security & auth, 52 against 43

Also in its favour

  • No key needed to call it
  • Open source

Watch for

No MCP server, CLI or llms.txt of its own. The docs point agents to the separate chrome-devtools-mcp project

Verdicts

Browserbase

x402 sessions at x402.browserbase.com with no account, $0.12 an hour, unused minutes refunded. The hosted MCP setup page passes the API key as ?browserbaseApiKey= in the URL.

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.

Before you call either

Browserbase

  1. Use x402.browserbase.com when you have a wallet and no key. Terminate the session to get unused minutes refunded
  2. Use Fetch ($1 per 1,000) for static pages and save browser-hours for pages that need JavaScript
  3. Close sessions explicitly. Each session bills at least one minute, and idle ones keep billing
  4. Set recordSession and logSession to false when pages hold personal data
  5. On 429, wait retry-after seconds before creating another session

Puppeteer

  1. Install with npm i puppeteer, which downloads a matching Chrome for Testing. Use puppeteer-core to bring your own browser
  2. Prefer page.locator() over page.$(). Locators wait for the element to be visible and stable before acting
  3. Read pages with page.accessibility.snapshot({interestingOnly: true}) rather than full HTML to keep output short
  4. Catch TimeoutError separately from TargetCloseError. The first can be retried, the second needs a new page or browser
  5. Packages are ESM only since 25.0.0. Use import puppeteer from 'puppeteer' rather than require
