## Which one, for what

### Browserbase (BB)

Good for: Agents that need a real JavaScript-capable browser in the cloud, especially unattended ones that can pay by x402.

Ahead on:
- Reliability, 90 against 40
- Payments & pricing, 90 against 42
- Maintenance & community, 92 against 81
- Transparency & trust, 71 against 54

Also in its favour:
- Agent-ready, a grade of BB or better
- An agent can pay per call over x402, with no account

Watch for: The hosted MCP setup page passes the API key as `?browserbaseApiKey=` in the URL

### Pomerado (B)

Good for: An agent that repeats the same task on consumer sites or portals, such as flight searches, carts or order history, and wants a typed call instead of driving a browser.

Ahead on:
- Schema & documentation, 86 against 80
- Agent ergonomics, 83 against 75
- Security & auth, 69 against 43

Also in its favour:
- Open source

Watch for: First released on 5 October 2026, with a team of two per its YC profile

## Verdicts

**Browserbase.** x402 sessions at x402.browserbase.com with no account, $0.12 an hour, unused minutes refunded. The hosted MCP setup page passes the API key as `?browserbaseApiKey=` in the URL.

**Pomerado.** An agent can find and run 46 public read-only website tools with no account, and signed-in calls get scoped, expiring keys, idempotency keys and a documented code for every failure. Pomerado is 12 days old, with no status page or security.txt, and its homepage lists bank and government portals that its builds refuse.

## Before you call either

### Browserbase

1. Use x402.browserbase.com when you have a wallet and no key. Terminate the session to get unused minutes refunded
2. Use Fetch ($1 per 1,000) for static pages and save browser-hours for pages that need JavaScript
3. Close sessions explicitly. Each session bills at least one minute, and idle ones keep billing
4. Set `recordSession` and `logSession` to false when pages hold personal data, and pass `allowedDomains` to keep a session on known sites
5. On 429, wait `retry-after` seconds before creating another session

### Pomerado

1. Try public read-only tools at https://mcp.pomerado.ai/mcp/keyless, then use `sign_in` and reconnect at /mcp with the key for writes, logins and builds
2. Call `find_website_tool` with a query and `site_url`, and check `possible_matches` before starting a build
3. Send an `idempotency_key` with every run that writes, and on `outcome_unknown` read the website back before calling again
4. Give the person the job's `answer_url` for website logins and codes. Don't take passwords in chat
5. Save a run's result when it arrives. It is returned once and erased after 60 minutes if unread
