# Agent Browser integration

> Use Agent Browser with Browserbase for fast, CLI-driven browser control optimized for AI agents.

[Agent Browser](https://github.com/vercel-labs/agent-browser) is a headless browser automation CLI built for AI agents. It provides a fast Rust-powered command-line interface with accessibility-first semantics, making it ideal for LLM-driven browser control.

Agent Browser has built-in Browserbase support via its `-p browserbase` provider flag, giving your agents cloud browser sessions with no local browser required.

## Key features

* **Accessibility tree snapshots** with element refs (`@e1`, `@e2`) optimized for LLM consumption
* **Full browser control** via simple CLI commands — click, type, fill, screenshot, navigate
* **Built-in Browserbase provider** — connect to cloud browsers with a single flag
* **Rust-powered performance** with sub-millisecond parsing overhead
* **Semantic locators** — find elements by ARIA role, text, label, placeholder, or test ID

## How it works

```
AI Agent → agent-browser CLI → Browserbase Cloud Browser → Target Website → Data Back
```

Your AI agent calls `agent-browser` commands to control a Browserbase cloud browser. The `snapshot` command returns an accessibility tree with element references that the agent can use for deterministic interactions.

## When to use this

* **AI agent tooling** — give LLMs a CLI interface to control browsers
* **Automated data extraction** — extract data using accessibility tree snapshots
* **Form filling and testing** — interact with web forms via simple commands
* **Screenshot and PDF generation** — capture pages from cloud browsers
