Overview
Browserbase is a San Francisco–based AI browser infrastructure platform founded in 2024 by Paul Klein IV. The platform provides managed, serverless headless browser hosting in the cloud, enabling developers and AI agents to automate web interactions at scale without managing browser infrastructure. Core primitives include Browser-as-a-Service sessions (Playwright/Puppeteer/Selenium compatible), Web Data APIs (Search and Fetch), an Identity layer (CAPTCHA solving, proxies, stealth mode), session observability (replay, live view, logs), and an MCP server for direct LLM-to-browser control. Browserbase also publishes Stagehand, an open-source AI browser automation framework with 21.5K GitHub stars, and Director, a no-code workflow builder. More than 10,000 companies and 100,000 developers use the platform, collectively running tens of millions of browser sessions monthly. The company has raised $67.5M and is valued at approximately $300M.
