ComfyUI is an open-source, node-based interface for running Stable Diffusion and related generative models locally.
Instead of simple text boxes and sliders, you build visual workflows by connecting “nodes” — each node handles a specific task like loading a model, applying a LoRA, encoding prompts, sampling, or upscaling. It’s designed for people who want full control over how images are generated.
It runs locally on your machine (Windows, macOS, Linux) and supports modern diffusion models like SD 1.5, SDXL, and community variants.
Most AI image tools hide complexity behind a simple UI. That’s great for beginners — but limiting for serious creators.
