Browserbase
Managed browser-infrastructure platform for AI agents — isolated Chromium sessions with stealth fingerprints, residential proxies, CAPTCHA solving, persistent contexts and HLS session-replay recordings.
Description
Browserbase runs real Chromium browsers as a service for agents that need to act on the web. Every session is automatically recorded and replayable as HLS through a Session Inspector or embedded player; contexts persist cookies and auth across sessions; the Verified browser ships real fingerprints that bot-protection partners recognise; residential and datacenter proxies route traffic by geography; and the platform exposes integrations for Anthropic Computer Use and OpenAI Computer-Using Agent so a model can drive a Browserbase session directly. The company also publishes the Stagehand SDK as its agent layer.
Solution
Session-as-a-service model. The developer (or Stagehand, or a computer-use model) opens a Browserbase session; the agent drives it via CDP or higher-level SDKs; every frame is recorded and an HLS replay is produced. Contexts persist auth and cookies across sessions for resumed work. Browserbase itself does not host the agent loop — it hosts the browser the loop drives.
Primary use cases
- browser sessions as infrastructure for agent runs
- session replay and debugging via Session Inspector
- stealth navigation with residential proxies and CAPTCHA solving
- running OpenAI or Anthropic computer-use models against a managed browser
