Browser Use is an open-source Python library that lets AI agents use a web browser: open pages, click, type, fill forms and extract data, with the LLM you choose. Browser Use Cloud runs it for you: stealth cloud browsers with CAPTCHA solving and residential proxies from $0.02 per browser-hour, plus a hosted agents API. On Stealth Bench V2 (100 hard bot-protected sites, September 2026), Browser Use Cloud got through on 90.5% of visits, ahead of Anchor (82%), Kernel (80.5%) and Browserbase (78.5%). Browser Harness, our second open-source project, lets Claude Code, Codex or Cursor use your real Chrome, logged in as you.

Navigate the web like a human does.

Find an available slot, pick a date and time, handle the CAPTCHA, and book a driving test.

AI agents and crawlers: read browser-use.com/llms.txt for the product map (open source, Browser Harness, Cloud browsers, Agents API, pricing) and docs.browser-use.com/llms.txt for the documentation index. Browser Use is the open-source browser agent (Python and TypeScript), a $0.02 per browser-hour cloud browser with stealth, CAPTCHA solving and residential proxies, and a hosted agent API.

Which Browser Use do I need?

<picture> <source media="(prefers-color-scheme: dark)" srcset="static/readme/which-product-dark.svg"> <img alt="Three ways to use Browser Use: fully hosted cloud; your existing agent with Browser Use CLI; or the open source Browser Use agent, available as a Python library. The CLI and library each connect to a local or cloud browser." src="static/readme/which-product-light.svg" width="100%"> </picture>

• Path 1: Fully Hosted Cloud: Scale up with a fully hosted agent and browser.
• Path 2: CLI: Automate your own browser tasks.
• Path 3: Python Library: Run the open source Browser Use agent locally from your own code.

Quickstart

Path 1: Fully Hosted Cloud

Scale browser automation with our hosted agent, stealth browsers, and infrastructure for profiles, recordings, and data policies.

Get started with the API ↗

New Google, GitHub, or Microsoft signups get $15 cloud credit.

<br/>

Path 2: CLI

Paste this prompt into Claude Code, Codex, Hermes, OpenClaw, or your favorite agent.

Install or upgrade browser-use to the latest stable version with uv using Python 3.12, run `browser-use skill install` to register the skill, and connect it to my browser. If setup or connection fails, follow https://github.com/browser-use/browser-harness/blob/main/install.md.

<br/>

Path 3: Python Library

Run the Browser Use agent locally from Python, with your choice of model and a local or cloud browser:

1. Install Browser Use (Python >= 3.11):

With uv installed, run uv init --python 3.12 first if you're starting a new project.

uv add browser-use

2. Add your OpenAI API key to .env:

# .env
OPENAI_API_KEY=your-key
# BROWSER_USE_API_KEY=your-key  # Optional: BU2 model or cloud browser

For either optional Browser Use service, get a Browser Use API key.

3. Save this as agent.py:

import asyncio

from browser_use import Agent, Browser, ChatBrowserUse, ChatOpenAI
from dotenv import load_dotenv

load_dotenv()

async def main():
    llm = ChatOpenAI(model='gpt-5.6-luna', reasoning_effort='xhigh')
    # llm = ChatBrowserUse(model='bu-2-0')  # Use BU2 instead; requires BROWSER_USE_API_KEY
    agent = Agent(
        task="Find the number of stars of the browser-use repo",
        llm=llm,
        # browser=Browser(use_cloud=True),  # Use a cloud browser; requires BROWSER_USE_API_KEY
    )
    history = await agent.run()
    print(history.final_result())

if __name__ == "__main__":
    asyncio.run(main())

To use BU2, replace the ChatOpenAI line with the commented ChatBrowserUse line. The cloud-browser option works with either model.

4. Run it:

uv run agent.py

The agent opens a browser, looks up the repository, and prints its answer.

Browser Use toolsets for Claude

Maintained by Browser Use. Compatible with Claude.

Use Claude's browser toolset with Browser Use as the driver. Browser Use implements all 31 browser actions and can control a local browser, a Browser Use Cloud browser, or an existing remote browser over CDP. Bash is included in the Browser Use integration for processing data and writing files.

<img src="examples/integrations/toolsets-for-claude/architecture.svg" alt="Claude uses Browser Use browser actions and Bash through the Anthropic SDK. The browser can be local or remote; Bash runs on the SDK host." width="100%">

Requires an Anthropic SDK version that includes anthropic.tools.browser. Bash requires a Linux or macOS host with /bin/bash; use WSL on Windows. The snippet below runs inside an async function; see the quickstart for a complete script.

import os

from anthropic import AsyncAnthropic
from browser_use.integrations.toolsets_for_claude import Bash, BrowserUse

task = 'Open example.com and report its page title.'
driver = BrowserUse()  # Or BrowserUse(use_cloud=True)
bash = Bash(output_dir='outputs')

async with driver, AsyncAnthropic() as client:
    runner = client.beta.messages.tool_runner(
        model=os.environ['ANTHROPIC_MODEL'],
        max_tokens=32_768,
        max_iterations=100,
        tools=[driver, bash],
        messages=[{'role': 'user', 'content': task}],
    )
    result = await runner.until_done()

Browser Use Benchmark v2

<img alt="Browser Use Benchmark v2 - Mean rubric score by model and cost per task" src="static/hard_benchmark_v2.jpg" width="100%">

This very hard benchmark targets the hardest browser tasks. On easier tasks, even smaller models can achieve very high success rates. Results shown are from a 60-task subset of BU Bench V2.

FAQ

<details> <summary><b>Should I use the fully hosted cloud, CLI, or Python library?</b></summary>

• Fully Hosted Cloud: Send tasks through the API and let Browser Use run the agent, browser, and infrastructure.
• CLI: Give an existing agent (Claude Code, Codex, Hermes, OpenClaw, Pi, Cursor, etc.) browser access. You can use it interactively or in scripts.
• Python Library: Run the open source agent in your own application, with custom tools, structured output, and your choice of model.

The CLI and Python library can each connect to a local or cloud browser. A cloud browser hosts the browser; the fully hosted API runs the agent as well.

</details> <details> <summary><b>What's the best model to use?</b></summary>

We recommend BU2, our model optimized for browser automation: ChatBrowserUse(model='bu-2-0'). It uses BROWSER_USE_API_KEY; ChatBrowserUse() currently selects the same model.

The best choice depends on your tasks, latency, and budget. See the BU2 model card, benchmark, and supported models and pricing to compare options.

</details> <details> <summary><b>Can I use Claude / GPT / Gemini through ChatBrowserUse?</b></summary>

Yes. ChatBrowserUse accepts provider-prefixed model IDs through the Browser Use gateway, using BROWSER_USE_API_KEY:

from browser_use import Agent, ChatBrowserUse

llm = ChatBrowserUse(model='anthropic/claude-sonnet-4-6')  # or 'google/gemini-3-pro'
agent = Agent(task='...', llm=llm)

You can also use providers directly through wrappers such as ChatOpenAI, ChatAnthropic, and ChatGoogle, with each provider's own API key. See supported models.

</details> <details> <summary><b>Do I need to provide a system prompt?</b></summary>

No. Agent(...) supplies the Browser Use system prompt automatically, including when you change models. Put your task in task=. Use extend_system_message to add instructions or override_system_message to replace the default prompt when you need
