Powerful, modular node-based interface for Stable Diffusion and other diffusion models, with an extensible graph workflow system.

Features

ComfyUI is a powerful and modular diffusion model interface that uses a node-based graph system for building image generation workflows. Unlike traditional UIs, ComfyUI lets you chain nodes together for fine-grained control over every step—from loading models and applying LoRAs to running multiple samplers in sequence. It supports Stable Diffusion, SDXL, Flux, and many other models, with an active community creating custom nodes and sharing workflows. ComfyUI also exposes an OpenAI-compatible API for integration with other tools.
