Information
# Human Quickstart **1. Create environment with [uv](https://docs.astral.sh/uv/) (Python>=3.11):** \`\`\`bash uv init \`\`\` **2. Install Browser-Use package:** \`\`\`bash # We ship every day - use the latest version! uv add browser-use uv sync \`\`\` **3. Get your API key from [Browser Use Cloud](https://cloud.browser-use.com/dashboard/api) and add it to your \`.env\` file (new signups get $10 free credits):** \`\`\` # .env BROWSER_USE_API_KEY=your-key \`\`\` **4. Download chromium using playwright's shortcut:** \`\`\`bash uvx playwright install chromium --with-deps --no-shell \`\`\` **5. Run your first agent:** \`\`\`python from browser_use import Agent, Browser, ChatBrowserUse import asyncio async def example(): browser = Browser( # use_cloud=True, # Uncomment to use a stealth browser on Browser Use Cloud ) llm = ChatBrowserUse() agent = Agent( task="Find the number of stars of the browser-use repo", llm=llm, browser=browser, ) history = await agent.run() return history if __name__ == "__main__": history = asyncio.run(example()) \`\`\` Check out the [library docs](https://docs.browser-use.com) and the [cloud docs](https://docs.cloud.browser-use.com) for more!

# FAQ
What's the best model to use?
We optimized **ChatBrowserUse()** specifically for browser automation tasks. On avg it completes tasks 3-5x faster than other models with SOTA accuracy. For other LLM providers, see our [supported models documentation](https://docs.browser-use.com/category/llm-integration).Can I use custom tools with the agent?
Yes! You can add custom tools to extend the agent's capabilities: \`\`\`python from browser_use.tools import Tool @Tool() def custom_tool(param: str) -> str: """Description of what this tool does.""" return f"Result: \{param\}" agent = Agent( task="Your task", llm=llm, browser=browser, use_custom_tools=[custom_tool], ) \`\`\` See our [Custom Tools documentation](https://docs.browser-use.com/custom-tools) for more examples.Can I use this for free?
Yes! Browser-Use is open source and free to use. You only need to choose an LLM provider (like OpenAI, Google, ChatBrowserUse, or run local models with Ollama).How do I handle authentication?
Check out our authentication examples: - [Using real browser profiles](https://github.com/browser-use/browser-use/blob/main/examples/browser/real_browser.py) - Reuse your existing Chrome profile with saved logins - If you want to use temporary accounts with inbox, choose AgentMail - To sync your auth profile with the remote browser, run \`curl -fsSL https://browser-use.com/profile.sh | BROWSER_USE_API_KEY=XXXX sh\` (replace XXXX with your API key) These examples show how to maintain sessions and handle authentication seamlessly.How do I solve CAPTCHAs?
For CAPTCHA handling, you need better browser fingerprinting and proxies. Use [Browser Use Cloud](https://cloud.browser-use.com) which provides stealth browsers designed to avoid detection and CAPTCHA challenges.How do I go into production?
Chrome can consume a lot of memory, and running many agents in parallel can be tricky to manage. For production use cases, use our [Browser Use Cloud API](https://cloud.browser-use.com) which handles: - Scalable browser infrastructure - Memory management - Proxy rotation - Stealth browser fingerprinting - High-performance parallel execution
