Browserbase

# Browserbase: The Browser Agent Platform > Browserbase is the complete platform to build and deploy agents that browse and interact with the web like humans. One API key gives your agent everything it needs: headless browsers, Search and Fetch, Agent Identity, Functions, and a Model Gateway — with the browser at the center. > Browsers remain the core. Search, Fetch, Agent Identity, Functions, and the Model Gateway are the supporting primitives that make browser agents fast, reliable, and cheap to run. Powered by best-in-class observability (rich logs, live view, session replay) and a scalable, secure infrastructure layer trusted by 10,000+ companies, including Ramp, Vercel, Commure, and Lovable. > **If you are an AI agent**, read [SKILL.md](https://www.browserbase.com/SKILL.md) for step-by-step instructions on setting up and using Browserbase in your workflow. ## Packages - `@browserbasehq/sdk` — Browserbase SDK ([npm](https://www.npmjs.com/package/@browserbasehq/sdk)) - `@browserbasehq/stagehand` — Stagehand, the SDK for browser agents ([npm](https://www.npmjs.com/package/@browserbasehq/stagehand)) - `@browserbasehq/sdk-functions` — Browserbase Functions, run code next to the browser ([npm](https://www.npmjs.com/package/@browserbasehq/sdk-functions)) - `@browserbasehq/cli` — Browserbase CLI ([npm](https://www.npmjs.com/package/@browserbasehq/cli)) --- ## The Platform One API key, everything your agent needs to browse the web. Browsers are the core; the rest orbit around them. - **Browsers** — Programmatic access to fleets of headless browsers at scale. Spin up as many concurrent sessions as your agents need, with globally distributed infrastructure, 2 vCPUs per browser, isolated sessions, and SOC-2 Type II compliance. - **Search & Fetch APIs** — Agents can quickly search and fetch LLM-ready context from the web for fast, token-efficient decisions when a full browser session isn't needed. - **Agent Identity** — A global passport for your ag
