ComfyUI vs Stable Diffusion WebUI
Pick ComfyUI if you want the node-graph diffusion GUI (the published Midjourney/Runway stack). Pick AUTOMATIC1111 if you want the Gradio form-based WebUI.
Facts checked 20 Oct 2026. License, language, and GitHub activity come from the catalog or the project's own repo. "Not in the catalog row" means the public catalog dump does not store that number.

Self-hosting and resource needs
Both are on /stacks/comfyui-image. ComfyUI is Comfy-Org/ComfyUI. AUTOMATIC1111 is AUTOMATIC1111/stable-diffusion-webui. Invoke is the Apache-2.0 studio named next to them. You still bring checkpoints. A GPU workstation is the honest path. Neither has a one-click c17 Railway template.
