Custom Node Manager

The Custom Node Manager allows you to install, manage, and remove community node packs directly from the InvokeAI UI — no manual file copying required.

Accessing the Node Manager

Click the Nodes tab (circuit icon) in the left sidebar, between Models and Queue.

Installing a Node Pack

1. Navigate to the Nodes tab
2. On the right panel, select the Git Repository URL tab
3. Paste the Git URL of the node pack (e.g. https://github.com/user/my-node-pack.git)
4. Click Install

The installer will:

• Clone the repository into your nodes directory
• Load the nodes immediately — no restart needed
• Import any workflow .json files found in the repository into your workflow library (tagged with node-pack:<name> for easy filtering)

The install progress and results are shown in the Install Log at the bottom of the panel.

Installing Python Dependencies

The installer does not automatically run pip install for requirements.txt or pyproject.toml. Auto-installing dependencies into the running InvokeAI environment can pull in incompatible package versions and break the application.

If a node pack ships a requirements.txt or pyproject.toml, you’ll see a warning toast after installation. Install the dependencies yourself by following the instructions in the node pack’s documentation (typically pip install -r requirements.txt from inside an activated InvokeAI environment, but check the pack’s README first). After installing, click the Reload button so the new dependencies take effect.

Security Warning

Custom nodes execute arbitrary Python code on your system. Only install node packs from authors you trust. Malicious nodes could harm your system or compromise your data.

Managing Installed Nodes

The left panel shows all installed node packs with:

• Pack name
• Number of nodes provided
• Individual node types as badges
• File path on disk

Reloading Nodes

Click the Reload button to re-scan the nodes directory. This picks up any node packs that were manually added to the directory without using the installer.

Uninstalling a Node Pack

Click the Uninstall button on any node pack. This will:

• Remove the node pack directory
• Unregister the nodes from the system immediately
• Remove any workflows that were imported from the pack
• Update the workflow editor so the nodes are no longer available

No restart is required.

Scan Folder Tab

The Scan Folder tab shows the location of your nodes directory. Node packs placed there manually (e.g. via git clone) are automatically detected at startup. Use the Reload button to detect newly added packs without restarting.

Troubleshooting

Node pack fails to install

1. Verify the Git URL is correct and accessible
2. Check that the repository contains an __init__.py file at the top level
3. Review the Install Log for error details

Nodes don’t appear after install

1. Click the Reload button
2. Check that the node pack’s __init__.py imports its node classes
3. Check the server console for error messages

Workflows show errors after uninstalling

If you have user-created workflows that reference nodes from an uninstalled pack, those workflows will show errors for the missing node types. Reinstall the pack or remove the affected nodes from the workflow.
