How to choose

What to check before you pick

  1. Session model: how long a browser session can live, and whether cookies and logins persist between runs.
  2. Control surface: Playwright or Puppeteer compatibility, an SDK in your language, or an MCP server.
  3. Hosting: a managed cloud, self-hosting from open source, or a local browser on your own machine.
  4. Observability: session recordings, logs and live views for debugging what the agent did.
  5. Pricing unit: per browser hour, per session or per request. Check each vendor's pricing page before you commit.

This checklist is general advice. Check each vendor's docs and pricing page for current details.
