Frequently asked

What is Browserbase?

Browserbase is a cloud browser platform that lets AI agents browse and interact with the web like humans, providing managed browsers plus Search, Fetch, Identity, and observability primitives behind a single API.

Does Browserbase handle CAPTCHAs and logged-in sites?

Yes. Its Agent Identity layer is designed to navigate past anti-bot systems, CAPTCHAs, and authentication walls so agents can reach the roughly 85% of the web that APIs cannot.

The platform's browser automation framework, Stagehand, is open source, as is the Browser CLI; the managed cloud infrastructure is a hosted product.
