• Browserbase Infrastructure service Sold on its own

• Director Application Sold on its own Freely available

  Director turns plain-English instructions into browser agents that can run on a schedule.

Inside Browserbase

• Browserbase Agents AI agent Included with the parent

  Managed browser agent created from a natural-language prompt and run with one API call; it navigates sites, fills forms and returns structured JSON, with browsers, search, verified identity and proxies included.

• Browserbase Search API API service Included with the parent

  Real-time web search API for agents that returns ranked, token-optimised results (URL, title and favicon per page) so an agent can pick which sites to fetch or browse next.

• Browserbase Fetch API API service Included with the parent

  API that reads a URL live at request time and returns it as clean markdown, HTML or JSON for an agent's context, with ads and navigation stripped and an Extract option for structured fields.

• Browserbase Runtime Infrastructure service Included with the parent

  Sandboxed, isolated hosting for agent code deployed to Browserbase (Browserbase Functions), so an agent runs next to the browser session it controls instead of on a separate server.

• Browserbase Model Gateway API service Included with the parent

  Routes a Stagehand agent's model calls to OpenAI, Anthropic and Gemini through the Browserbase API key, handling billing, retries and rate limits, with tokens charged at the providers' own prices.

• Browserbase Identity Infrastructure service Included with the parent

  Gives each Browserbase session a cryptographically verified agent credential through Web Bot Auth, so partner sites and anti-bot providers let the agent in, with CAPTCHA solving and reusable logged-in contexts.

• Browserbase Observability Infrastructure service Included with the parent

  Debugging view over every Browserbase agent session: live view, action-by-action replay, structured logs of network requests, console output and errors, and traces of each agent decision.
