# Comfy Desktop FAQ

> Common questions and troubleshooting tips for Comfy Desktop

## General Questions

<Accordion title="What is the difference between Comfy Desktop and Legacy Desktop?">
  Comfy Desktop is a complete rewrite that acts as a **multi-installation manager**. Unlike Legacy Desktop which was a single-install application, Comfy Desktop lets you install, manage, and run multiple ComfyUI versions side by side. It also adds snapshots and model download management.

  For users of Legacy Desktop, check the [Migration Guide](/installation/desktop/usage/migrate) to transfer your existing setup.
</Accordion>

<Accordion title="Is Comfy Desktop open source?">
  Yes! The source code is available on [GitHub](https://github.com/Comfy-Org/Comfy-Desktop).
</Accordion>

<Accordion title="Does Comfy Desktop replace the Portable/Manual install?">
  Comfy Desktop is one of several installation options. You can still use the **Portable (Windows)** install, **Manual Install**, or **Comfy Cloud** depending on your needs. Desktop is recommended for most users due to its ease of use and features like one-click updates and snapshot management.
</Accordion>

## Installation & Setup

<Accordion title="What are the system requirements?">
  See [system requirements](/installation/system_requirements) for full details.

  * **Windows:** Windows 10+, NVIDIA GPU with CUDA support
  * **macOS:** macOS 13+ (Ventura), Apple Silicon (M1+)
  * **Linux:** Ubuntu 22.04+, NVIDIA GPU with CUDA recommended
  * **Disk:** At least 4.85 GB per standalone installation
  * **RAM:** 8 GB minimum, 16 GB recommended
</Accordion>

<Accordion title="Can I install Comfy Desktop without admin rights?">
  On **Windows**, the standalone installation does not require admin rights. On **macOS**, you'll need admin rights for the initial system-wide installation. On **Linux**, admin rights are needed for system dependencies but the app itself runs in user space.
</Accordion>

<Accordion title="How do I download Comfy Desktop?">
  Download the latest version from the official [ComfyUI Download page](https://comfy.org/download).
</Accordion>

<Accordion title="Can I have both Legacy Desktop and Comfy Desktop installed?">
  Yes, they can coexist. However, we recommend migrating your installations to the new Comfy Desktop and eventually uninstalling Legacy Desktop. See the [Migration Guide](/installation/desktop/usage/migrate).
</Accordion>

## Usage

<Accordion title="How do I add a new ComfyUI installation?">
  Open the Comfy Desktop app, click **Add Installation**, and choose the type:

  * **Standalone** — Fresh install with bundled Python
  * **Git Clone** — Link an existing git repository
  * **Portable** — Import a portable install (Windows)
  * **Cloud** — Connect to Comfy Cloud
</Accordion>

<Accordion title="Can I run multiple ComfyUI versions at the same time?">
  Yes! Comfy Desktop is designed for this. Each installation runs in its own isolated environment with its own Python and dependencies. You can launch them simultaneously in separate windows.
</Accordion>

<Accordion title="Where are my models, custom nodes, and settings stored?">
  Each installation is self-contained:

  * **Standalone:** All data is inside the installation folder
  * **Git Clone:** Data is in the ComfyUI `models/`, `custom_nodes/`, and `user/` folders within the repository
</Accordion>

<Accordion title="How do snapshots work?">
  Comfy Desktop automatically creates a snapshot before every update. Snapshots capture:

  * Custom nodes and their versions
  * Model files
  * Settings and configuration

  You can browse and restore any snapshot from the app's **Snapshots** section.
</Accordion>

## Troubleshooting

<Accordion title="The app won't start after installation">
  1. **Windows:** Try running as administrator once
  2. **macOS:** If you see a security warning, go to **System Settings → Privacy & Security** and click **Open Anyway**
  3. **Linux:** Make sure `fuse2` is installed (`sudo apt install fuse2`)
  4. Check the [Downloads page](https://comfy.org/download) for the latest version
</Accordion>

<Accordion title="My GPU is not detected">
  * Ensure your NVIDIA drivers are up to date
  * On Linux, verify CUDA toolkit is installed
  * Check that the installation type supports GPU (Standalone and Git Clone do; Cloud connections use remote GPU)
</Accordion>

<Accordion title="An installation fails to update">
  * Check your internet connection
  * Try taking a manual snapshot first via the app menu
  * If the issue persists, restore to a previous snapshot and try again
</Accordion>

<Accordion title="How do I uninstall Comfy Desktop?">
  Comfy Desktop and its installations are separate on disk. To fully remove:

  1. **Delete the installations** from within the app (right-click → Remove) or delete the installation folders manually
  2. **Uninstall the app** using your system's standard method (Add/Remove Programs on Windows, drag to Trash on macOS, package manager on Linux)
