ComfyUI (Workflow)
Node-based image generation — maximum control, maximum flexibility
📋 Overview
ComfyUI is a node-based image generation interface that provides maximum control and flexibility — allowing users to build custom workflows by connecting nodes. Unlike SD WebUI (which is tab-based), ComfyUI uses a node graph where each operation is a node. This provides unlimited flexibility but has a steeper learning curve.
