General Questions

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 to transfer your existing setup.
Yes! The source code is available on GitHub.
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.

​
Installation & Setup

See 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
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.
Download the latest version from the official ComfyUI Download page.
Yes, they can coexist. However, we recommend migrating your installations to the new Comfy Desktop and eventually uninstalling Legacy Desktop. See the Migration Guide.

​
Usage

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
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.
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
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.

​
Troubleshooting

  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 for the latest version
  • 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)
  • 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
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)
