Browserbase is cloud browser infrastructure for AI agents. It gives agents real headless browsers to log into sites, navigate dynamic pages, fill in forms and pull data from websites that have no API.

**Key features:**

- Browser-as-a-Service for running fleets of headless browsers in parallel.
- Search API for agent-oriented web search from a single query.
- Fetch API that converts any URL into HTML, JSON or markdown.
- Agent API for running managed browser agents with a connected model.
- CAPTCHA solving, stealth mode and agent identity for login walls and bot checks.
- Session observability, Functions runtime and sandboxes for deploying agents.

Browserbase is used through API keys and also maintains the open-source Stagehand SDK. The Free plan includes 3 concurrent browsers, 1 browser hour and 1,000 Search and Fetch calls. Developer is $20/month with 100 browser hours and Startup is $99/month with 500 browser hours and 100 concurrent browsers, with overage billed per use. The custom Scale plan adds HIPAA BAA, DPA and SSO.
