Browserbase — Cloud Browser Infrastructure for Agents
Running Chrome at scale for an agent is its own infrastructure problem — profiles, proxies, captchas, fingerprinting, crashes. Browserbase sells this as a service: spin up an isolated Chrome session on demand, get a WebSocket URL, drive it with Playwright or Stagehand. Integrates with all major agent frameworks and has become the default browser backend for production web agents.

Frequently asked questions
Why not just run headless Chrome in a container?
You can, but you'll burn weeks on: fingerprint stealth, proxy rotation, CAPTCHA handling, session storage, crash recovery, and concurrency limits. Browserbase handles all of that so your agent code stays focused on the task.
What's session recording?
Every Browserbase session is recorded as a replayable video + DOM timeline. When an agent fails on step 47 of a workflow, you can rewind and see exactly what the page looked like — invaluable for debugging.
How does it price?
Per-session with included minutes, then per-minute overages. Enterprise tiers include dedicated proxies, residential IPs, and SSO. Check Browserbase pricing page for current rates.
