How to Use ComfyUI Manager

1. Accessing the Manager

From the main menu of ComfyUI, click the “Manager” button.

2. Using the Manager Menu

Upon accessing the manager, you will see various options:

  • Install Custom Nodes: Lets you view and manage custom nodes.
  • Install Models: Provides a list of models you can install.
  • Use local DB: When toggled on, this feature ensures that the application uses data stored on your device instead of fetching data from the internet.
  • Fetch Updates: This option fetches any update data for the custom nodes you have locally. It is important to note that fetching update data and actually updating the nodes are separate processes.

3. Installing Nodes or Models

When you click on either ‘Install Custom Nodes’ or ‘Install Models’, an installer dialog box will appear.

For nodes:

For models:

In this dialog:

  • Installed: Indicates that the item is already installed on your system.
  • Install: Click this button to install the respective node or model.
  • Try Install: For nodes whose installation details might be ambiguous or unverified, this button allows you to attempt the installation. Use with caution.

4. Customizing Node Display

In the manager menu, you’ll find a Badge option. This allows you to customize how the nodes are displayed:

  • Badge: Nickname: This displays the nickname or a short name for the custom nodes.
  • Badge: ID Nickname: Along with the nickname, this option will also show the internal ID of the node, providing more detailed information.

How to register your custom node into ComfyUI-Manager

  • Add an entry to custom-node-list.json located in the root of ComfyUI-Manager and submit a Pull Request.
  • NOTE: Before submitting the PR after making changes, please check Use local DB and ensure that the extension list loads without any issues in the Install custom nodes dialog. Occasionally, missing or extra commas can lead to JSON syntax errors.
  • The remaining JSON will be updated through scripts in the future, so you don’t need to worry about it.

Custom node support guide

  • Currently, the system operates by cloning the git repository and sequentially installing the dependencies listed in requirements.txt using pip, followed by invoking the install.py script. In the future, we plan to discuss and determine the specifications for supporting custom nodes.
  • Please submit a pull request to update either the custom-node-list.json or model-list.json file.
  • The scanner currently provides a detection function for missing nodes, which is capable of detecting nodes described by the following two patterns.
    • Or you can provide manually node_list.json file.
    "ExecutionSwitch": ExecutionSwitch,
    "ExecutionBlocker": ExecutionBlocker,

    "UniFormer-SemSegPreprocessor": Uniformer_SemSegPreprocessor,
    "SemSegPreprocessor": Uniformer_SemSegPreprocessor,
  • When you write a docstring in the header of the .py file for the Node as follows, it will be used for managing the database in the Manager.
    • Currently, only the nickname is being used, but other parts will also be utilized in the future.
    • The nickname will be the name displayed on the badge of the node.
    • If there is no nickname, it will be truncated to 20 characters from the arbitrarily written title and used.

@description: This extension offers various detector nodes and detailer nodes that allow you to configure a workflow that automatically enhances facial details. And provide iterative upscaler.
  • Special purpose files (optional)
    • node_list.json – When your custom nodes pattern of NODE_CLASS_MAPPINGS is not conventional, it is used to manually provide a list of nodes for reference. (example)
    • requirements.txt – When installing, this pip requirements will be installed automatically
    • install.py – When installing, it is automatically called
    • uninstall.py – When uninstalling, it is automatically called
    • disable.py – When disabled, it is automatically called
      • When installing a custom node setup .js file, it is recommended to write this script for disabling.
    • enable.py – When enabled, it is automatically called
    • All scripts are executed from the root path of the corresponding custom node.

Support of missing nodes installation

  • When you click on the Install Missing Custom Nodes button in the menu, it displays a list of extension nodes that contain nodes not currently present in the workflow.

ComfyUI-Manager Troubleshooting

  • If your git.exe is installed in a specific location other than system git, please install ComfyUI-Manager and run ComfyUI. Then, specify the path including the file name in git_exe =  in the ComfyUI-Manager/config.ini file that is generated.
  • If updating ComfyUI-Manager itself fails, please go to the ComfyUI-Manager directory and execute the command git update-ref refs/remotes/origin/main a361cc1 && git fetch --all && git pull.
  • Alternatively, download the update-fix.py script from update-fix.py and place it in the ComfyUI-Manager directory. Then, run it using your Python command. For the portable version, use ..\..\..\python_embeded\python.exe update-fix.py.
  • For cases where nodes like PreviewTextNode from ComfyUI_Custom_Nodes_AlekPet are only supported as front-end nodes, we currently do not provide missing nodes for them.
  • Currently, vid2vid is not being updated, causing compatibility issues.
