Browserbase
Cloud browsers, search and fetch APIs for agents that act on the web
Browserbase is a platform for running agents that browse and act on websites. One API key covers cloud browsers that agents control to navigate pages and fill forms, a Search API for finding relevant sites, a Fetch API that returns a page as HTML, JSON or markdown, a runtime for deploying agents, and an agent identity layer for logins and CAPTCHAs. Sessions come with logs, live view and session replay. Browserbase works with Playwright, Puppeteer and Selenium, and maintains Stagehand, an open-source (MIT) browser automation framework whose act, extract and observe primitives sit on top of Playwright-style control.
Use Cases
- Fill and submit forms on vendor and government portals that have no API
- Pull receipts, statements and reports from supplier dashboards
- Research many sites in parallel and return structured data
- Run agents that click through your own product and alert when a flow breaks
- Replay a session to check exactly what an agent did on a site
