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.

Features

  • Multiple installs, side by side – run as many independent ComfyUI setups as you like, each with its own version, models, and custom nodes. Switch between them without conflicts.
  • Isolated, GPU-ready environments – each install ships a relocatable Python with PyTorch and GPU wheels prebuilt. No pip/uv failures, no CUDA roulette at install time.
  • One-click updates – update ComfyUI (and custom nodes) to the latest version in place. No terminal, no git, no re-downloading the multi-gigabyte environment.
  • Snapshots & rollback – back up an install and restore it if an update or a custom node breaks something.
  • Bring your existing setup – adopt and migrate existing ComfyUI installations (portable, git, or a previous desktop install) in place.
  • Cross-platform – Windows, macOS, and Linux.
  • Built-in auto-updates – the app keeps itself current.
  • Works without system Git – bundles a tiny Python + pygit2 bootstrap so clones work on a clean machine.

An ecosystem that moves faster than any company could.

Over 5,000 community-built extensions – totaling 60,000+ nodes – plug into ComfyUI and extend what it can do. When a new open model launches, ComfyUI implements it, and the community customizes and builds it into their workflows immediately. When a research paper drops a new technique, an extension appears within days.

Why professionals choose Desktop

Unlimited Customization

Install any of 5,000+ community extensions, totaling 60,000+ nodes. Build your own custom nodes. Integrate with Photoshop, Nuke, Blender, Houdini, and any tool in your existing pipeline.

Any model. No exceptions.

Run every open-source model – Wan 2.1, Flux, LTX and more. Finetune, customize, control the full inference process. Or use partner models like Nano Banana and Grok.

Your machine. Your data. Your terms.

Run entirely offline. No internet connection required after setup. Your workflows, your models, your data.

Free. Open Source. No ceiling.

No feature gates, no trial periods, no "pro" tier for core functionality. No vendor can lock you in or force you off the platform. Build your own nodes and modify ComfyUI as your own.
