Browserbase
Managed headless-browser infrastructure for AI agents at scale.
About
Browserbase is managed headless-Chromium infrastructure: instead of provisioning your own browser fleet, you request a browser from the API and get a real sandboxed cloud session with stealth/anti-bot handling, residential proxies, CAPTCHA solving, session recording, and a live view. You drive it with standard Playwright or Puppeteer over CDP.
It is the commercial counterpart to Stagehand, the company's open-source MIT browser-automation framework with natural-language act/extract/observe primitives — Stagehand runs locally for free or points at Browserbase cloud for production scale.
Pricing: free tier (1 browser hour, 3 concurrent), Developer $20/mo (100 hours), Startup $99/mo (500 hours, 100 concurrent). Honest limits: it is proprietary infrastructure with vendor lock-in, and costs scale with browser-hours at serious volume.
