Browser Use Desktop is an open-source desktop application that gives AI agents direct, reliable access to a Chromium browser for web automation, data extraction, form filling, and multi-step internet tasks. Built on the Browser Use Python framework (16,000+ GitHub stars as of early 2026), it packages the agent-browser bridge into a standalone app with a visual interface for monitoring agent activity in real time.

It supports integration with LLM providers including OpenAI, Anthropic Claude, and local models through LangChain, enabling developers to pair any large language model with autonomous browser control.
