## Which one, for what

### Browser Use (BB)

Good for: An agent that wants to hand a whole browser task to a hosted agent and get a result back, or that needs a low-cost cloud browser over CDP, and for unattended agents that can pay by x402.

Ahead on:
- Payments & pricing, 90 against 60

Also in its favour:
- An agent can pay per call over x402, with no account
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: The privacy policy says inputs are used to train Browser Use's AI models, with no opt-out described outside Enterprise zero data retention

### Chrome DevTools MCP (BB)

Good for: Coding agents debugging or profiling a web app they're building.

Ahead on:
- Agent ergonomics, 83 against 78
- Maintenance & community, 93 against 77
- Transparency & trust, 81 against 65

Also in its favour:
- No key needed to call it

Watch for: Usage statistics go to Google by default until you pass `--no-usage-statistics`

## Verdicts

**Browser Use.** The hosted cloud accepts x402 top-ups in USDC on Base with no account or API key, and publishes prices, rate limits and three OpenAPI documents. The privacy policy says inputs are used to train Browser Use's models, API keys have no documented scopes, and no prompt-injection guidance was found in the docs.

**Chrome DevTools MCP.** Performance traces, network inspection, heap snapshots and Lighthouse audits in one server. Usage statistics go to Google by default until you pass `--no-usage-statistics`.

## Before you call either

### Browser Use

1. Send the key as `X-Browser-Use-API-Key` with no Bearer prefix. A Bearer header returns 401
2. Stop browsers with `PATCH /api/v4/browsers/{id}` and `{"action":"stop"}`. Closing CDP or the SDK client leaves the browser billing
3. Poll `GET /runs/{id}/status`, not the full run, and wait for the returned Retry-After on 429, which can be 300 seconds at the edge
4. Before resubmitting after a timeout, read the existing run's status. The server keeps running and may already have submitted a form
5. With a wallet and no key, call x402.api.browser-use.com on `/api/v2` or `/api/v3` routes. A task stops with INSUFFICIENT_CREDITS if credit runs out mid-run

### Chrome DevTools MCP

1. Pass `pageId` on every page tool. Call `list_pages` first to get it
2. Start with `--slim` for plain browsing, or turn off categories you don't need
3. Run with `--isolated` for untrusted sites. The default profile persists between runs
4. Use `filePath` on large outputs such as traces and snapshots to keep them out of context
5. Add `--no-usage-statistics` if the operator hasn't agreed to Google telemetry
