Headless browser cloud built for AI agents

Browserbase is cloud infrastructure that runs headless Chromium browsers on demand for AI agents and automation workflows, exposing Playwright, Puppeteer, and Selenium endpoints with built-in session replay, residential proxies, CAPTCHA solving, and stealth fingerprints. It also hosts Stagehand and a Model Gateway, letting teams build browser-using agents without maintaining their own fleet of Kubernetes-managed Chromium instances.

AI-powered web browser automation with Playwright

Stagehand is an open-source browser automation framework combining Playwright with AI vision to let agents interact with web pages using natural language. Instead of writing brittle CSS selectors, describe actions like 'click the login button' or 'fill in the email field' and Stagehand identifies and interacts with the right elements. Built by Browserbase, it provides act(), extract(), and observe() primitives for building reliable browser agents that understand page context visually.
