Also from Browserbase

• Browserbase Agents AI agent

  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

  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

  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

  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

  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

  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

  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.

• Director Application

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