How Browserbase works

Browserbase is a browser sandbox, not a code runtime: it runs fleets of real cloud browsers that your agent drives with Playwright, Puppeteer, Selenium or Browserbase's own Stagehand SDK. On top of the raw browser it layers the parts that make web automation reliable at scale, Agent Identity for stealth, captcha solving, session recording and replay, a Model Gateway and a runtime. It works with agent frameworks like LangChain and CrewAI and is SOC2 compliant with US and EU regions.

Pricing in practice & watch-outs

Billing is primarily per browser-hour, roughly $0.10 to $0.12 depending on plan, with a free tier (3 concurrent browsers, 1 browser-hour) and paid Developer and Startup plans that raise concurrency, browser hours and data retention. A browser hour covers a lot (a typical scrape runs in under two minutes), but at high concurrency the hours add up, so model your expected session volume. It is cloud-only, so there is no on-prem option, and stealth and captcha features sit on the paid tiers.
