About ComfyUI

"The most powerful Stable Diffusion interface"

ComfyUI is the most powerful open-source node-based GUI for running Stable Diffusion and other AI image generation models locally, offering unprecedented control over every step of the generation pipeline through a visual node graph interface. Unlike simpler interfaces, ComfyUI exposes the complete diffusion process — allowing users to chain models, apply ControlNet, mix LoRAs, implement custom samplers, and build reusable generation workflows of arbitrary complexity. Professional AI artists and technical users who demand maximum flexibility and cutting-edge experimental features use ComfyUI as their primary AI art production environment.
