What is Browserbase?
Browserbase is a headless browser platform that gives AI agents and developers cloud browsers with captcha solving, proxies and the Stagehand SDK. Instead of running Chrome on your own servers, you start browser sessions through an API and control them with Playwright, Puppeteer, Selenium or Stagehand, Browserbase's open-source framework for AI browser automation. The company raised a $40 million Series B in 2025 and powers many browser agents.
Browserbase's value is handling the hard parts of browsing at scale: concurrency, stealth, proxies, captchas, session recording and debugging. Newer products add Search and Fetch APIs, agent runs and a model gateway. Developers use it to build AI agents that fill forms, book things or research online, to scrape and extract data, to test web apps and to automate workflows on sites without APIs.
Main Features
- Launch headless cloud browsers on demand through an API.
- Control sessions with Playwright, Puppeteer, Selenium or Stagehand.
- Run up to 100 concurrent browsers on Startup and 250+ on Scale.
- Solve captchas and route traffic through proxies on paid plans.
- Replay and debug sessions with recordings and live view.
- Call Search and Fetch APIs to get web results and page content.
- Run hosted agents and access models through the model gateway.
