UPDATE — 2025-10-28

• New: Clicking a node’s name now copies its GitHub repository URL to the clipboard (label styled as a link with a hand cursor).

Custom Node Updater for ComfyUI

A simple desktop tool (Tkinter) to manage ComfyUI custom nodes: clone, update (git pull), switch to a specific branch, install requirements, and delete selected nodes—all with logs and a scrollable list.

Features

• Clone node from a GitHub URL into ComfyUI/custom_nodes/.
• Update selected repositories via git pull.
• Install requirements from each node’s requirements.txt using the embedded Python (python_embeded/python.exe).
• Delete selected nodes safely (restricted to ComfyUI/custom_nodes/, with confirmation).
• Switch to branch: enter a branch name and update the selected node to that branch (git fetch --all --prune + git switch or create a tracking branch if needed).
• Show current branch next to each node's name (displayed in its own column after the name).
• Copy GitHub URL on click: click a node’s name to instantly copy its GitHub repo URL to the clipboard.
• Scrollable node list and persistent console panel (split view) so logs remain visible when resizing the window.

Additionally, a convenience launcher script run_CustomNodeUpdater.bat is included to start the app quickly on Windows.

Installation (Quick setup)

• Copy CustomNodeUpdater.py and run_CustomNodeUpdater.bat into the root of your ComfyUI folder — the same directory that contains the python_embeded/ folder.
• Ensure python_embeded/python.exe exists (or update the path in the script if your layout differs).
• Make sure Git is installed (or set a full path/alias if needed).

Requirements

• Git available in your system PATH.
• Python: the script uses an embedded interpreter at python_embeded/python.exe for installing requirements. Adjust paths if your setup differs.
• A standard ComfyUI folder structure with ComfyUI/custom_nodes/.

Installation

1. Place this repository next to (or inside) your ComfyUI setup so that ComfyUI/custom_nodes/ is reachable by the script.
2. Ensure python_embeded/python.exe exists (or update the path in the script).
3. Make sure Git is installed.
4. (Windows) Double-click run_CustomNodeUpdater.bat to launch; or run the script via Python.

Usage

1. Update database – scans ComfyUI/custom_nodes/ for Git repos and lists them.

2. Clone node – paste a GitHub URL and click CLONE NODE.

3. Select repositories (checkboxes) and choose:

   • GIT PULL SELECTED
   • INSTALL REQUIREMENTS TO SELECTED
   • DELETE SELECTED NODES (permanent; only inside custom_nodes/)

4. Switch to branch – in a row’s input field, enter a branch name (e.g., main, dev, feature-x) and click UPDATE TO BRANCH.

5. Copy GitHub URL – click on the node’s name to copy its repository URL to the clipboard (confirmation appears in the log panel).

Note: The current branch for each node is displayed next to its name, so you can quickly see what branch is active.

Branch switching details

• The app runs git fetch --all --prune, then tries git switch <branch>.
• If the local branch does not exist, it creates it tracking origin/<branch>.
• This preserves local changes; it does not hard-reset to origin/<branch>.

If you prefer a force update (local branch exactly equals origin/<branch>), you can modify the function to use git checkout -B <branch> origin/<branch>.

Safety notes

• Deletions are confirmed and limited to ComfyUI/custom_nodes/ to avoid accidental removal outside this folder.
• Logs are shown in a console panel for transparency.

Troubleshooting

• Git not found: ensure Git is installed and accessible in PATH.
• requirements.txt not found: some nodes don’t need dependencies; the installer will skip them.
• Branch not found: verify the branch name exists on the remote.
• Clipboard not working: some desktop environments may restrict clipboard access; check OS permissions.
