Open Source Multi-Agent Windows Desktop Automation LLM Developer Tools Research

Overview

UFO is a UI-focused agent framework designed to operate Windows applications by interpreting user requests in natural language and acting directly on graphical interfaces. It coordinates multiple specialized agents that observe the screen, plan steps, and execute actions across native and third-party Windows apps. The system combines large language models with screen understanding and control APIs, enabling tasks that span multiple applications, such as moving data between Word, Excel, and Outlook. It is primarily aimed at researchers and developers exploring desktop automation and OS-level AI agents.

Use it every day

Honestly didn't expect to like it this much. Integration with LLM providers is exactly what I needed, and open source and extensible. I do wish reliability varies with complex UIs, but I reach for it almost every day now and it just clicks.

Solid for our team

We rolled this out across the team last quarter and multi-agent architecture with clear role separation. Integration with LLM providers fits neatly into how we already work, and logging and step-by-step traces removed a step we used to do by hand. Requires technical setup and API keys, which is the main caveat, but it has held up under daily use.

Does the job

Pretty happy overall. Natural language task input just works and open source and extensible. but no dealbreakers — I'd recommend it to a friend without hesitating.
