Browsers that don't get stuck

Browserbase is the infrastructure layer for agentic apps: ephemeral, scalable cloud browsers your code controls via a simple SDK, with the reliability production demands.

Who it's for: Founders and engineers shipping AI agents, scrapers, and test suites that need real browsers in the cloud.

Key features

Managed sessions

Launch isolated browsers via API in milliseconds.

Stealth mode

Avoid bot detection with fingerprinting and proxy handling.

Session replay

Debug exactly what your agent saw, after the fact.

Scales to thousands

Run concurrent sessions without babysitting servers.

The honest take

✓ What works

  • Removes the hardest part of browser agents
  • Excellent debugging via replay
  • Stealth handles most anti-bot setups
  • Pairs perfectly with Stagehand

✗ What doesn't

  • Costs add up at high volume
  • Requires engineering to integrate
  • Not a no-code tool
  • Vendor lock-in on session format

Verdict

If you're building anything agentic that touches the web, Browserbase is the 'don't roll your own' call. Pair it with Stagehand and you've got a production browser stack in an afternoon.
