# ComfyUI

> ComfyUI is an open-source, node-based AI workflow engine for generating images, videos, 3D assets, and audio using generative AI models.

ComfyUI is a powerful, open-source node-based interface for building and running generative AI workflows. It lets users visually connect nodes on a canvas to create complex pipelines for image, video, 3D, and audio generation — all without writing code. Built and maintained by the original core team at Comfy Org, it runs locally on your machine for fast iteration, low cost, and full control. ComfyUI is 100% free and open source, and is used by millions of creators, animators, and developers worldwide.

- **Node-Based Workflow Builder** — *Connect nodes visually on a canvas to construct AI pipelines; branch, remix, and adjust every step at any time.*
- **Reusable Workflows** — *Save and share entire workflows; exported files carry embedded metadata so anyone can drag and drop them to instantly rebuild the workflow.*
- **Live Preview** — *See results in real time as you adjust your workflow, enabling faster iteration and instant visual feedback.*
- **Custom Nodes** — *Extend ComfyUI by building or installing custom nodes to add new functionality and tailor the tool to your needs.*
- **Runs Locally** — *Designed for performance, ComfyUI runs directly on your machine for faster processing, lower costs, and complete data control.*
