Anchor Browser and Hyperbrowser score within a point of each other on agent readiness, 67.3 (B) and 66.9 (B). Hyperbrowser leads on payments & pricing, maintenance & community and transparency & trust. Both do browser automation. Hyperbrowser accepts x402. Anchor Browser doesn't.

## 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
- Schema & documentation, 80 against 68
- Agent ergonomics, 73 against 67
- Security & auth, 54 against 44

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

### Hyperbrowser (B)

Good for: Agents that need a cloud browser by the minute plus cheap fetch and search, especially wallet-holding agents with no account.

Ahead on:
- Payments & pricing, 94 against 60
- Maintenance & community, 79 against 57
- Transparency & trust, 64 against 51

Also in its favour:
- An agent can pay per call over x402, with no account
- Runs on your own machine

Watch for: The official MCP server's last npm release is 1.0.25 of 13 April 2025, and it isn't in the official MCP registry

## 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.

**Hyperbrowser.** Sessions, Fetch and Search can be bought by x402 at api.hyperbrowser.ai with USDC on Base or Solana and no account, and unit prices are public. The official MCP server was last published in April 2025, no request rate limits or SLA are published, and the privacy notice covers only the website.

## 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

### Hyperbrowser

1. With a wallet and no key, POST to https://api.hyperbrowser.ai/x402/session and read the `PAYMENT-REQUIRED` header. Sessions are prepaid for 5 to 60 minutes with no refund
2. Save the x402 creation response. It holds the only copy of the connection tokens, and `managementToken` is what stops the session
3. Stop sessions explicitly in cleanup code. Browser time bills per second until the timeout
4. Use Fetch at $0.001 a page for static pages and keep browser sessions for pages that need interaction
5. Add `&keepAlive=true` to `wsEndpoint` to reconnect after a CDP disconnect. Treat that URL as a secret because it carries the session token
