Which one, for what

Browserbase BB

Good 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 82
  • Payments & pricing, 90 against 40
  • Maintenance & community, 92 against 82
  • Transparency & trust, 71 against 62

Also in its favour

  • An agent can pay per call over x402, with no account

Watch for

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

Browserless BB

Good 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 80
  • Security & auth, 53 against 43

Also in its favour

  • Runs on your own machine

Watch for

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

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.

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.

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

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()

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
