When a website redesigns its layout or changes a class name, traditional automation scripts break instantly.\n\n**browser-use** is an open-source Python library developed to solve this fragility. By pairing Large Language Models (LLMs) with browser automation tools like Playwright, it enables AI agents to navigate, interact with, and complete multi-step tasks on any website dynamically.\n\n`browser-use`\n\nacts as an intelligence layer between AI models and browser drivers. Instead of requiring developers to write hardcoded click paths, `browser-use`\n\nfeeds visual and DOM context to an LLM. The LLM then determines the next action—such as clicking a button, entering text, or scrolling—until the target goal is completed.\n\nAI agents powered by `browser-use`\n\ndo not rely on hardcoded selectors. They read page state dynamically, allowing them to fill out complex forms, solve interactive UI flows, and handle site changes without breaking.\n\n`browser-use`\n\nincludes built-in support for the Model Context Protocol (MCP). This allows AI assistants like Claude Desktop, Cursor, and CLI coding agents to trigger browser automation natively as part of their toolset.\n\nThe library is model-agnostic. You can power your browser agents using commercial APIs (like OpenAI GPT-4o or Anthropic Claude 3.5 Sonnet) or run them entirely offline using local LLMs via Ollama.\n\nGetting started takes only a few lines of Python code:\n\n``` python\nfrom langchain_openai import ChatOpenAI\nfrom browser_use import Agent\nimport asyncio\n\nasync def main():\n    agent = Agent(\n        task=\"Find a flight from NYC to London on Kayak for next Tuesday\",\n        llm=ChatOpenAI(model=\"gpt-4o\"),\n    )\n    result = await agent.run()\n    print(result)\n\nasyncio.run(main())\n```\n\nAs software workflows shift from manual point-and-click operations to autonomous agentic execution, libraries that bridge LLMs with real-world interfaces become fundamental infrastructure. By giving AI models full control over browser environments, `browser-use`\n\nis unlocking a new generation of intelligent web automation.\n\n*Want to build your own browser AI agent?
