DevUI for Microsoft Agent Framework

agent-framework-devui is a lightweight, standalone sample application providing a debug UI for the Microsoft Agent Framework. It offers an OpenAI-compatible API server for running and testing AI agents and workflows, supporting directory-based discovery, in-memory entity registration, and a gallery of sample entities. It also includes an OpenAI Proxy feature, enabling direct testing of OpenAI models via the interface while keeping API keys secure on the server. Primarily designed as an 'inner-loop' developer tool, it visualizes agent execution, including reasoning, actions, and observations.
