closed(cloud browser fleet/session infra)

note

companion Stagehand SDK IS open source (Apache/MIT) but the Browserbase service being scored is the closed managed platform

The product scored here is the managed browser-infrastructure service, which is closed and proprietary. The companion Stagehand SDK is open source, but it is a client to the service rather than the service itself, so it does not make the scored platform open.

  One API key across a hosted Browser API, Search API, Fetch API, Functions and Model Gateway. Stagehand documented as a separate SDK - "The SDK for browser agents. Natural language selectors, self-healing actions, and caching at scale ... Built by Browserbase" - on its own docs site. No self-hosting option for the platform itself.
