Overview
ComfyUI is a node-based interface and execution engine for diffusion image and video generation. Users connect nodes into reusable graphs, save workflows as JSON, load custom nodes, and run supported models on local hardware or through Comfy services. The core project is aimed at creators, technical artists, and developers who need explicit control over models, parameters, and outputs. It is self-hostable and licensed under GPL-3.0. The official organization also publishes a Python SDK and a command-line tool for scripting and deployment.
