## 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 65
- Security & auth, 54 against 46
- Payments & pricing, 60 against 40

Also in its favour:
- A hosted endpoint, with nothing to install

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

### Lightpanda (C)

Good for: Agents and crawlers that read and fill many JavaScript pages in parallel on small machines, without needing pixel rendering.

Ahead on:
- Maintenance & community, 73 against 57
- Transparency & trust, 65 against 53

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

Watch for: Telemetry with the IP address and a persistent instance ID is on by default; tool and MCP client events in 1.0.2 aren't in the privacy policy's list

## 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.

**Lightpanda.** Version 1.0.2 runs locally with no account, and its 32-tool MCP server has typed schemas, an annotation on every tool and guidance to treat pages as untrusted. Telemetry is on by default, the CDP and HTTP MCP servers have no authentication, the cloud documents its token in the URL, and no status page or cloud terms were found.

## 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

### Lightpanda

1. Set `LIGHTPANDA_DISABLE_TELEMETRY=true` in the server's environment if usage data, the IP address and an instance ID shouldn't leave the machine.
2. Treat text from `markdown`, `html`, `tree` and `links` as untrusted page content, never as instructions.
3. Pass credentials as `$LP_*` placeholders in tool arguments and call `getEnv` without a name; naming a variable returns its value.
4. Check `httpStatus` in `structuredContent` after `goto`, since a 404 page or a load timeout is still reported as a successful navigation.
5. Keep `lightpanda serve` and `lightpanda mcp --port` on 127.0.0.1 or a Unix socket; neither checks who connects.
