ComfyUI

ComfyUI is a node-based interface and inference engine for generative media. A workflow can combine a model, prompts, reference images, conditioning, upscaling, and export in a reusable graph. That control is useful when a creative task has many steps or needs consistent settings across a batch. The open-source application can run locally, but model files, GPU memory, and optional external services have their own requirements. The graph also makes provenance easier to inspect than a single opaque prompt, although community nodes introduce maintenance and security risk. Keep working workflows versioned and test extensions before production use.
