## Which one, for what

### Anchor Browser (B)

Good for: Agents that must work inside signed-in accounts, with managed identities, MFA handling and a human sign-in link, and agents that need to start with no human signup.

Ahead on:
- Reliability, 80 against 58
- Schema & documentation, 80 against 74
- Payments & pricing, 60 against 40

Watch for: No service agreement or API terms found. anchorbrowser.io/terms is a website terms of use dated 16 March 2025

### 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.

Ahead on:
- Maintenance & community, 83 against 57
- Transparency & trust, 61 against 51

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

**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
