Browser Use

Browser-Use Skill

Browser-Use is a powerful library that allows AI agents to control web browsers (Chromium, Chrome, Edge) using LLMs. It handles DOM processing, element interaction, and vision-based decision making.

Core Capabilities

• Autonomous Navigation: Agents can navigate to any URL and follow links.
• Element Interaction: Clicking, typing, scrolling, and form filling.
• Vision Integration: Uses screenshots to help the agent understand the page layout.
• DOM Extraction: Intelligent extraction of text and structured data from pages.
• Authentication: Can use existing browser profiles to stay logged into websites.

Installation

The skill requires Python 3.11+ and the browser-use package.

pip install browser-use playwright
playwright install chromium

Basic Usage

To run an agent, you need an LLM provider (OpenAI, Anthropic, Google, etc.) and a task.

from browser_use import Agent, ChatOpenAI
import asyncio

async def main():
    agent = Agent(
        task="Find the latest news about SpaceX on Google",
        llm=ChatOpenAI(model="gpt-4o"),
    )
    result = await agent.run()
    print(result)

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

Best Practices

• Be Specific: Give the agent clear, step-by-step instructions in the task string.
• Use Vision: Set use_vision=True when the page layout is complex or requires visual confirmation.
• Wait for Actions: The agent automatically waits for pages to load, but you can add explicit waits in the task if needed.
• Browser Profiles: Use user_data_dir to preserve login sessions and cookies.
• Sandboxes: For production, consider using the @sandbox wrapper provided by Browser-Use Cloud.

Troubleshooting

• Cloudflare/Captchas: If blocked, try using headless=False or connecting to a real browser instance.
• Element Not Found: Ensure the agent has enough steps (max_steps) and that the page has fully loaded.
• Timeout: Adjust step_timeout or llm_timeout for slow pages or complex reasoning.
