Which one, for what

Puppeteer BB

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

Ahead on

  • Reliability, 80 against 57
  • Payments & pricing, 60 against 32

Also in its favour

  • Agent-ready, a grade of BB or better
  • No key needed to call it
  • No incidents deducted, where Skyvern loses 3 points for them

Watch for

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

Skyvern B

Best for Agents that must finish a multi-step job on sites with logins, 2FA and forms, where stored credentials, saved workflows and cached scripts matter more than raw browser time.

Ahead on

  • Schema & documentation, 88 against 81
  • Agent ergonomics, 76 against 67
  • Security & auth, 59 against 52

Also in its favour

  • A hosted endpoint, with nothing to install
  • Runs on your own machine
  • Free to start without a card

Watch for

Every API key and OAuth token has full organisation authority. The docs state there are no read-only, per-endpoint or per-resource keys

Verdicts

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.

Skyvern

The hosted MCP server annotates every tool as read-only or destructive and can advertise a 29 or 32-tool subset in place of 114, and the API has a written six-month deprecation policy. Every key and OAuth token carries full organisation authority, with no read-only or scoped credential, and no request rate limits are documented.

Before you call either

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

Skyvern

  1. Connect to https://api.skyvern.com/mcp/x/lean or /x/operate, or send X-Skyvern-Scope, so the client loads 32 or 29 tools. The scope filters the list and does not limit permissions
  2. Use a separate Skyvern organisation for each blast radius. Any key or OAuth token can read and write stored credentials and delete workflows
  3. Never pass passwords to skyvern_act or skyvern_type. Store them as credentials and call skyvern_login
  4. Set max_steps on tasks, or x-max-steps-override on agent runs, to cap credits. A run that reaches the cap ends as timed_out
  5. On 503 from POST /v1/run/agents, wait Retry-After seconds. No run was created, so resubmitting is safe

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
