ComfyUI System Requirements (CPU, RAM, Disk)

ComfyUI is a powerful, modular, and node-based GUI for Stable Diffusion and other diffusion models. It provides a visual graph/nodes interface where users can design complex image generation workflows by connecting nodes. Each node represents a component of the generation pipeline — from loading checkpoints and text encoders to applying LoRAs, ControlNet, and samplers. With 118k+ GitHub stars, it is the most popular alternative to AUTOMATIC1111. It supports SD1.5, SDXL, SD3, Flux, and video generation models. All processing runs locally on your own GPU, giving you full privacy and unlimited generations.
