Browserbase
Summary
Headless browser infrastructure for AI agents — sessions, stealth, proxies, and live view, without running Chrome yourself.
Description
Browserbase runs browsers so your agents do not have to. It provides managed headless Chrome sessions accessible through standard automation libraries, with the operational problems — scaling, captchas, proxies, fingerprinting, session state — handled by the platform.
What it solves
- Scale. Spin up hundreds of concurrent browser sessions without managing containers.
- Stealth. Fingerprint management and residential proxies so automation is not blocked on sight.
- Authentication. Persistent contexts keep sessions logged in across runs.
- Observability. Live view of a running session, plus recordings and logs — invaluable when an agent silently does the wrong thing.
- File handling. Uploads and downloads within a session.
Stagehand
Browserbase maintains Stagehand, an open-source framework that mixes deterministic Playwright code with natural-language actions. You script the reliable parts and let the model handle the fragile ones, which is a much better fit for production than making everything an agent decision.
Access
Compatible with Playwright, Puppeteer, and Selenium, so existing scripts move over with a connection-string change. Free tier for development, usage-based pricing by browser-hour after that.
