What is Browserbase?
Browserbase is a cloud platform that gives AI agents a real browser to navigate websites. Instead of relying on APIs, an agent can log in, fill in forms, click through interactive pages and extract data, with the platform handling authentication, dynamic content and CAPTCHAs.
The platform is organized into primitives such as cloud browsers, Search API (finding relevant websites from one query), Fetch API (returning page content as HTML, JSON or markdown), runtime, identity, model access and observability. There is also open source tooling, including the Browse CLI and the Stagehand framework for browser automation. Typical uses are web data extraction, records verification, portal filings, document retrieval and monitoring sites for changes.
