## Overview

ComfyUI is a free, open-source, node-based tool for running AI image and video models. You build workflows by wiring nodes together, which gives you precise control over every model, parameter and output.

It runs locally on your own GPU, and Comfy also offers a desktop app and a paid cloud version. Its large community shares workflows and custom nodes, so it supports many open models and techniques soon after release.

## Key features

- Visual node-graph workflow builder
- Runs open image and video models locally
- Huge library of community workflows and custom nodes
- Reusable workflows for consistent output
- Desktop app plus optional Comfy Cloud

## Use it for

- Build a repeatable pipeline for consistent game icons or portraits

## Pricing

The local app is free and open source. Comfy Cloud and enterprise plans are paid and usage-based; check comfy.org for current pricing.
