Launching ComfyUI

Click any installation card to launch it. Comfy Desktop will:
  1. Start the ComfyUI backend process
  2. Wait for it to be ready
  3. Open a ComfyUI editor window
If the installation is already running, clicking the card brings the existing window to focus instead of starting a new instance.

Running Multiple Instances

You can launch multiple installations simultaneously. Each runs independently:
  • Each has its own Python environment
  • Each has its own ComfyUI version and custom nodes
  • Each runs on a different port
  • Each opens in its own window

Installation Actions

Right-click an installation card (or click the ⋮ icon) to access actions:

The Manage Panel

Selecting Manage on an installation opens the settings panel with several tabs:

Status Tab

Shows:
  • Current ComfyUI version
  • Disk space usage
  • Last launch time
  • Launch / Stop / Restart controls

Update Tab

  • Check for new ComfyUI versions
  • One-click update installation
  • Shows changelog for available updates

Snapshots Tab

  • View all saved snapshots
  • Restore to any previous state
  • Manual snapshot creation
  • Snapshot comparison (shows what changed between snapshots)

Settings Tab

Configure per-installation ComfyUI settings:
  • ComfyUI arguments — Custom CLI arguments (e.g., --gpu-only, --highvram, --listen 0.0.0.0)
  • Environment variables — Set custom environment variables for this installation
  • Model directories — Add external model directories
  • Launch settings — Configure extra ports, queue size, etc.

Editing an Installation

You can edit an installation’s name, path, and configuration after creation. Use the pencil icon (✏️) next to the installation name to rename it.

Snapshots

Comfy Desktop automatically creates a snapshot before each update. Snapshots capture:
  • The ComfyUI version (git commit hash)
  • All installed custom nodes (with versions)
  • Python package list

Viewing Snapshots

Go to the Snapshots tab in the Manage panel. Each snapshot shows:
  • Date and time it was created
  • ComfyUI version at that point
  • Whether it was auto-created or manual

Restoring a Snapshot

To restore to a previous state:
  1. Open the Manage panel for the installation
  2. Go to the Snapshots tab
  3. Click Restore on the snapshot you want to revert to
  4. Confirm — Comfy Desktop will roll back ComfyUI and all custom nodes

Manual Snapshots

You can also create snapshots manually before making significant changes, giving you a guaranteed rollback point.
