## Which one, for what

### Chrome DevTools MCP (BB)

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

Ahead on:
- Schema & documentation, 87 against 81
- Agent ergonomics, 83 against 67
- Security & auth, 63 against 52
- Transparency & trust, 81 against 70

Also in its favour:
- Runs on your own machine

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

### Puppeteer (BB)

Good for: Agents that write and run Node.js scripts against Chrome or Firefox.

Watch for: No MCP server, CLI or llms.txt of its own. The docs point agents to the separate chrome-devtools-mcp project

## Verdicts

**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`.

**Puppeteer.** Puppeteer is a stable, Apache-2.0 library on 25.13.0, with ten releases since 27 July 2026, typed APIs, locators that wait and retry, and accessibility snapshots an agent can read. It has no MCP server or llms.txt of its own, and 10 of the 20 most recent CI runs on main failed between 7 and 13 October 2026.

## Before you call either

### 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

### Puppeteer

1. Install with `npm i puppeteer`, which downloads a matching Chrome for Testing. Use `puppeteer-core` to bring your own browser
2. Prefer `page.locator()` over `page.$()`. Locators wait for the element to be visible and stable before acting
3. Read pages with `page.accessibility.snapshot({interestingOnly: true})` rather than full HTML to keep output short
4. Catch `TimeoutError` separately from `TargetCloseError`. The first can be retried, the second needs a new page or browser
5. Packages are ESM only since 25.0.0. Use `import puppeteer from 'puppeteer'` rather than `require`
