Browser Use — AI Agent Browser Automation

What is Browser Use?

Browser Use is a Python library that gives AI agents the ability to control web browsers. It uses vision-based element detection to understand page layout, supports multi-tab browsing, and works with any LLM — enabling agents to complete real web tasks autonomously.

Answer-Ready: Browser Use is an AI agent browser automation library that enables LLMs to control web browsers with vision-based element detection, multi-tab support, and natural language task execution. 50k+ GitHub stars.

Best for: AI agent developers who need web browsing capabilities. Works with: Claude, GPT-4o, Gemini, any LangChain-compatible model. Setup time: Under 3 minutes.

Core Features

1. Vision-Based Interaction

Browser Use screenshots the page and identifies interactive elements:

agent = Agent(
    task="Search for 'AI tools' on Google and click the first result",
    llm=llm,
)
# Agent sees the page, identifies search box, types, clicks results

2. Multi-Tab Support

agent = Agent(
    task="Open three tabs: GitHub, HN, and Reddit. Find the top AI post on each.",
    llm=llm,
)

3. Custom Actions

from browser_use import Agent, Controller

controller = Controller()

@controller.action("Save data to file")
def save_data(data: str, filename: str):
    with open(filename, 'w') as f:
        f.write(data)

agent = Agent(
    task="Scrape product prices and save to prices.csv",
    llm=llm,
    controller=controller,
)

4. Persistent Sessions

from browser_use import BrowserConfig

config = BrowserConfig(
    headless=False,        # Watch it work
    keep_open=True,        # Keep browser open after task
    cookies_file="cookies.json",  # Persist login
)
agent = Agent(task="...", llm=llm, browser_config=config)

5. MCP Server Mode

{
  "mcpServers": {
    "browser-use": {
      "command": "uvx",
      "args": ["browser-use-mcp-server"]
    }
  }
}

Use Browser Use as an MCP server in Claude Code or other MCP-compatible tools.

Use Cases

FAQ

Q: How does it compare to Playwright MCP? A: Playwright MCP provides low-level browser control. Browser Use adds AI vision and autonomous task execution on top of Playwright.

Q: Does it work with Claude Code? A: Yes, via MCP server mode. Install the browser-use-mcp-server package.

Q: Can it handle login-protected pages? A: Yes, with persistent cookies or by letting the agent perform the login flow.
