# What is Browserbase?

> The complete platform to build and deploy agents that browse and interact with the web like humans.

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 [headless browsers](/welcome/getting-started), [web search](/platform/search/overview), [page fetching](/platform/fetch/overview), [functions](/platform/runtime/overview), [model access](/platform/model-gateway/overview), and [identity](/platform/identity/overview).

All powered by best-in-class [observability](/platform/browser/observability/observability) — rich logs, live view, and session recordings across every agent step.

## Why Browserbase?

* **Agents need the full web.** Traditional APIs only cover \~15% of it. The rest is behind logins, JS rendering, CAPTCHAs, and interactive flows — that requires a browser.
* **One platform, not 5+ vendors.** Browsers, search, fetch, models, and deployment under one API key, one bill, and one debugger.
* **Unrestricted access.** [Agent Identity](/platform/identity/overview) gets your agents past bot detection and auth walls through partnerships with Cloudflare, Fingerprint, and more.
* **Faster, more secure execution.** [Functions](/platform/runtime/overview) run your code next to the browser with \< 5ms latency — no Temporal, no schedulers, and no containers.

## Stagehand

[Stagehand](https://docs.stagehand.dev/) is the SDK for browser agents. It combines Playwright-level control with AI primitives (`act`, `extract`, `observe`) that self-heal when pages change. It plugs into LangChain, CrewAI, Mastra, and more.
