Browserbase
Hosted headless browser cloud
Free tier + paidCode review, testing & securitybrowserbase.com
What it is
Managed headless browser infrastructure driven over CDP by Playwright, Puppeteer or Stagehand, with stealth mode, proxies, captcha handling and full session recording and replay. It handles concurrency so you never operate a browser fleet yourself. Browserbase also publishes and maintains Stagehand as its open-source automation layer.
Why it earns a slot
Gives CI and your agents a real browser without maintaining one, so end-to-end checks of AI-built flows run on every pull request rather than only on the laptop where they happened to work.
Know before you commit
The free tier is one browser hour per month, which is a handful of test runs. Budget for the $20 Developer plan almost immediately.
Neighbourhood
How Browserbase sits against the rest of the atlas — swaps, companions and the tools builders actually save alongside it.
