Which one, for what

Browserless BB

Best for Agents that need a real browser in the cloud with stealth, proxies and CAPTCHA solving, and teams that want the option of running the same server themselves.

Ahead on

  • Schema & documentation, 89 against 81
  • Agent ergonomics, 78 against 67

Also in its favour

  • A hosted endpoint, with nothing to install
  • Runs on your own machine
  • Free to start without a card

Watch for

REST and WebSocket routes take the API token as ?token= in the URL, which the docs give as the standard method

Puppeteer BB

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

Ahead on

  • Payments & pricing, 60 against 40
  • Maintenance & community, 89 against 82
  • Transparency & trust, 70 against 62

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

Browserless

An OpenAPI document, llms.txt and a 14-tool MCP server with annotations on every tool make the service easy for an agent to read, and the free plan needs no card. The API token travels in the URL query string by default, cloud tokens carry no scopes, and no machine payment route exists.

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

Browserless

  1. 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
  2. Close sessions as soon as the work is done. Browser time bills one unit per 30 seconds, rounded up, idle or not
  3. 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
  4. On 429, back off and retry. It means the plan's concurrency limit or queue is full, usually from sessions left open
  5. Match the path to the protocol. Use /chromium for CDP clients and /chromium/playwright only for playwright.connect()

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
