ComfyUI is a visual workflow engine for generating and processing images, video, audio and other model outputs. Its node graph lets users connect model components, reuse workflows and expose them through an API. The software can run locally on Windows, Linux or macOS; suitable hardware and model files are required. The code is open source under GPL-3.0. Comfy Cloud is a separate paid hosting option, and partner nodes may use paid external services. Model licenses and hardware requirements vary independently of the interface.
