About ComfyUI
ComfyUI is the most widely used open-source interface for generative image models. Instead of a form with settings, you build a graph of nodes: load a model, encode a prompt, sample, upscale, mask, and so on, which makes complex pipelines repeatable and shareable as workflow files. It usually supports new open models such as FLUX, Stable Diffusion, Wan and LTX within days, and thousands of community custom nodes extend it further. Partner nodes also call hosted models like Nano Banana. The desktop app and the core engine are free, GPL-licensed and run offline on Windows, macOS and Linux. Comfy Org also sells Comfy Cloud, a hosted version on rented GPUs with monthly plans, and a platform for deploying workflows as APIs. The learning curve is steep for beginners, but it suits power users and studios who want full control over every step.
Best for: Power users and studios who want full control over local image and video pipelines.
