Browserbase is a browser-agent platform that provides managed, headless Chromium browsers and supporting web primitives for AI agents and automation workloads. Customers use a single API key to spin up sessions, fetch and search the web, persist context, route LLM calls, and observe agent behavior across replays and logs. The company maintains the popular open-source Stagehand SDK, a Director UI for agent design, a Browse CLI, and an MCP server. Target customers are AI startups, agent developers, RPA teams, and enterprises running production web automation, with SOC 2 Type II and HIPAA options. Billing is usage-based with a free tier and paid plans on the pricing page.
