Node-based interface for Stable Diffusion and image generation pipelines
ComfyUI is a node-based graphical interface for image generation models, where each step of the pipeline is a node you wire together. That makes complex, repeatable workflows possible in a way form-based interfaces do not, and workflows can be exported and shared as files. It runs locally, supports a large custom-node ecosystem, and is widely used for advanced image and video pipelines. The trade-off is a steeper start: a blank canvas is less approachable than a prompt box.
