Browserbase documentation

What it does

A hosted headless-browser service (sessions, proxies, stealth, session recording) with Stagehand, its natural-language browser automation layer, so agents can navigate, act on and extract from web pages that plain HTTP fetching cannot reach.

Access and connection

Access requirements: free - the pricing page lists Free at $0/mo with "1 browser hour", 3 concurrent browsers, "15 minutes /session", "1,000 Search calls" and "1,000 Fetch calls"; Developer $20/mo ("100 browser hours then $0.12/browser hr"), Startup $99/mo ("500 browser hours then $0.10/browser hr"), Scale custom.
