AI product Open source
ComfyUI is an open-source AI content-creation engine and diffusion-model GUI, API, and backend developed by Comfy-Org. Its visual node-graph interface lets users build and reuse no-code workflows for image, video, audio, 3D, and text generation, editing, and processing, including workflows using diffusion models, VAEs, text encoders, LoRAs, ControlNets, adapters, and upscalers.
Workflows can be saved and loaded as JSON, exposed through App Mode, or integrated into applications through local API endpoints. The engine supports asynchronous queueing, partial graph re-execution, VRAM and RAM management, model offloading, quantized models, custom nodes, and fully offline core operation unless optional resources are requested.
It can run locally on Windows, Linux, and macOS through desktop, portable, or manual installations, with support for NVIDIA, AMD, Intel, Apple Silicon, and Ascend hardware. Comfy-Org also provides an official paid cloud version.

An open-source modular AI content-creation engine built around a visual node graph. Users connect nodes to create workflows for generating images, video, audio, 3D models, and text, with support for local hardware, diffusion models, quantization, LoRAs, ControlNets, and custom nodes.
Node-based local interface for connecting AI models, prompts, samplers, image operations, and output nodes to generate and process images.
