ComfyUI
100% FreeComfyUI is a highly advanced, node-based graphical user interface (GUI) designed to run Stable Diffusion and open video models (like Wan, Hunyuan, LTX, and CogVideo) locally. It offers infinite control over workflows, and has no recurring costs as it runs entirely on your own GPU.
Best for: Advanced power users who want local control and custom pipelines
