## Which one, for what

### agent-browser (B)

Good for: Coding agents with a shell that want short commands and compact snapshots.

Ahead on:
- Schema & documentation, 84 against 74
- Security & auth, 67 against 56
- Payments & pricing, 60 against 40

Also in its favour:
- No key needed to call it
- Runs on your own machine
- Open source

Watch for: The ten most recent CI runs on main, 1 to 8 October 2026, all concluded in failure. In the newest, Windows Rust tests and native end-to-end tests failed

### 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:
- Reliability, 58 against 48
- Maintenance & community, 83 against 70

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

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

**agent-browser.** Snapshots with element refs, a 29-tool default MCP profile and opt-in domain allowlists, action policies and content boundary markers suit agent use. The project is at 0.38.2 with no stable release, the ten most recent CI runs on main failed between 1 and 8 October 2026, and every security control is off by default.

**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

### agent-browser

1. Run `agent-browser install` once after `npm install -g agent-browser`. It downloads Chrome for Testing
2. Take a fresh `snapshot -i` after any navigation. Refs survive same-document changes only
3. Pass `--json` for machine-readable results and `--max-output` to cap page text
4. Set `--allowed-domains`, `--action-policy` and `--content-boundaries` for untrusted sites. None is on by default, and the allowlist rejects `--profile`, `--cdp` and `--restore`
5. Start MCP with `agent-browser mcp`, and add profiles such as `--tools core,network` only when needed

### 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
