# Comfy Desktop Overview

> Learn about Comfy Desktop — a modern desktop app for managing multiple ComfyUI installations

**Comfy Desktop** is a desktop application that lets you install, manage, and launch multiple ComfyUI instances from a single launcher.

To put it simply: **Comfy Desktop** is the app that manages and launches **ComfyUI**, the node-based engine for generative AI. You don't install ComfyUI separately — Comfy Desktop handles the installation, Python environment, and dependencies for you. Each ComfyUI instance runs independently with its own version, custom nodes, and settings.

Comfy Desktop runs on **Windows 10+**, **macOS 13+ (Apple Silicon)**, and **Debian-based Linux**. Each standalone installation requires at least **4.85 GB** of disk space and **8 GB RAM (16 GB recommended)**. Check the platform-specific pages for full details.
