# Browserbase

> Managed headless browsers for AI agents, with Stagehand as the SDK

- Chromium sessions you connect to over CDP, with reusable contexts, an embeddable live view, extension loading and a download API
- Stagehand, its open-source TypeScript SDK, layers model-driven act/extract calls over ordinary Playwright
- Infrastructure is closed and priced per browser-hour, with residential proxy bandwidth billed separately
