Browserbase runs cloud browser infrastructure specifically built for AI agents, running real browser instances rather than simulating one, so an agent can handle login flows, CAPTCHAs, and dynamic UI changes the way a person browsing the site would.
That real-browser approach targets a specific gap most automation tools can't close: the company positions it as reaching roughly 85% of the web that APIs simply can't, login-protected dashboards, sites without a public API, pages that render content dynamically after load. The platform reports handling nearly 37 million browser sessions as of March 2026, and backs an open-source SDK called Stagehand that bridges traditional browser-testing precision with full agent autonomy.
A free tier covers standard use, and paid plans start around $20 a month for more concurrent sessions and browser hours. For a developer building an AI agent that needs to reliably navigate real, login-protected websites rather than relying on API access that doesn't exist, Browserbase's real-browser infrastructure addresses that specific reliability gap directly.
