What Is ComfyUI?

ComfyUI is a free, open-source engine for generating images, video, audio, 3D models and text with AI models that run on your own hardware. Instead of a form with a prompt box and a Generate button, it gives you a canvas of nodes: one loads a model, one encodes your prompt, one samples, one decodes the result into pixels, one saves the file. You wire them together, and the wiring is the program.

The project describes itself as "the most powerful and modular AI engine for content creation", and the adoption behind that line is real: more than 141,000 GitHub stars, nearly 17,000 forks, a GPL-3.0 license and a release roughly every week.…
