ComfyUI

ComfyUI is an open-source, node-based interface for image generation, primarily used with Stable Diffusion and other open-weight visual models. Users build pipelines by wiring graph nodes together, which makes it a powerful canvas for experimental workflows, ControlNet stacks, and complex compositions. Pre-built ComfyUI pipelines are also surfaced on platforms like Replicate. Together with Automatic1111 it is one of the most widely used local image-generation interfaces in the community.
