Comfy Desktop supports the comfy:// custom protocol for opening local workflow files directly from your browser or terminal. 
comfy://open?file=/path/to/workflow.json
Clicking a comfy:// link or running it from the command line will:
  1. Launch Comfy Desktop (if not already running)
  2. Open the specified workflow file in the ComfyUI editor
  3. Focus the existing window (if already running)
This works on all platforms:
  • macOS: Click a comfy:// link in any app
  • Windows/Linux: Click the link in a browser or run it from the terminal
Note: Deep links only work with local file paths. The feature requires Comfy Desktop to be installed as the protocol handler — it registers itself automatically during installation.
