Browserbase is a cloud platform that makes the web as reliable and programmable as APIs for AI agents. It provides real browsers as a service, allowing agents to navigate, log in, fill forms, and extract data from any website, including those behind login walls or with dynamic content. The platform offers a suite of primitives:
- Browser-as-a-Service: Spin up real browser sessions that agents can control programmatically. Handles authentication, CAPTCHAs, and unpredictable UI.
- Search API: Let agents find relevant websites based on a single query.
- Fetch API: Convert any URL into HTML, JSON, or markdown for quick context retrieval.
- Runtime: Scalable, sandboxed environments for deploying agents.
- Identity: Tools to authenticate agents so they navigate like a human.
- Models: Use any AI model with a single API key.
- Observability: Unified debugging across replays, logs, and prompts.
Browserbase also offers open-source tools like Stagehand (the most popular AI browser automation framework) and Browser CLI, enabling developers to build and deploy browser agents quickly. Use cases include automated testing, workflow automation, web data extraction, and large-scale research. The platform is used by companies like Microsoft, Clay, Amplitude, Ramp, Lovable, and DeepMind.
