Verdicts

Anchor Browser

The API has a public OpenAPI 3.1 document, per-unit prices and Agent Access, an unauthenticated flow that issues a trial API key without a dashboard account. No service agreement is published, only a website terms of use, and the documented CDP connection puts the API key in the URL.

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

Anchor Browser

  1. Send the key in the anchor-api-key header. For CDP, build wss://connect.anchorbrowser.io?apiKey=<key>&sessionId=<id> and keep that URL out of logs
  2. 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
  3. 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
  4. Connect the Anchor MCP server or Anchor (all), not both, because the docs say the pair duplicates tool names
  5. 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

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
