ComfyUI Free

ComfyUI — Node-Based AI Image Generation Workflow Studio

ComfyUI is a free, open-source, node-based interface for Stable Diffusion that gives creators total control over AI image generation. Instead of a simple prompt box, ComfyUI lets you build visual workflows where every step of the generation process is transparent and adjustable.

Because it is modular, ComfyUI supports advanced techniques like ControlNet, LoRA, and sophisticated inpainting. Artists and developers love it for its flexibility, reproducibility, and the vibrant community that shares reusable workflows.
