Which one, for what

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

  • Reliability, 82 against 58
  • Schema & documentation, 89 against 74

Also in its favour

  • Agent-ready, a grade of BB or better
  • 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

Notte B

Good for Teams that want hosted browsers together with agents, vaults for logins, personas with mailboxes and scheduled browser functions behind one key.

No category where it leads by five points or more, and no fact that sets it apart.

Watch for

status.notte.cc shows the Scrape API down on 15 of 90 days (about 6 hours in total) and CAPTCHA solving at 88.9 per cent availability

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.

Notte

Notte publishes an OpenAPI 3.1 contract for 100 operations, a hosted MCP server with eight tools and OAuth, and a free plan with $10 of credits and no card. Its status page records about six hours of Scrape API downtime in 90 days, and a bot check blocked our read of the terms and privacy policy.

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()

Notte

  1. Send Authorization: Bearer $NOTTE_API_KEY to https://api.notte.cc. A person creates the key in the console at console.notte.cc first
  2. Stop every session when the task ends. Sessions close after 3 idle minutes or 15 minutes in total by default, and the Free plan caps a session at 15 minutes
  3. Use https://api.notte.cc/mcp for browser work. Function and agent administration tools are only on https://api.notte.cc/mcp/full
  4. Back off on 429 and on 529, which means the cluster has too many sessions. The SDKs do not retry rate limits for you
  5. Download session replays within 24 hours. The recordings page says they are deleted after that

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.
