ComfyUI
Node-graph interface and engine for running diffusion models locally
What it is
ComfyUI is a local application and backend for building image, video, audio, and 3D generation pipelines by wiring nodes together in a visual graph. It runs open models such as Stable Diffusion, Flux, Wan, and Hunyuan on consumer GPUs with memory offloading and quantized weights, and exposes workflows through an API and a simplified App Mode. Artists and technical creators use it to control every step of a generation, from LoRAs and ControlNets to inpainting and upscaling, and extend it with community custom nodes.
