• standalone version
• select option: use windows default console window

2. Download scripts/install-manager-for-portable-version.bat into installed "ComfyUI_windows_portable" directory
3. double click install-manager-for-portable-version.bat batch file

Installation[method3] (Installation through comfy-cli: install ComfyUI and ComfyUI-Manager at once.)

RECOMMENDED: comfy-cli provides various features to manage ComfyUI from the CLI.

• prerequisite: python 3, git

Windows:

python -m venv venv
venv\Scripts\activate
pip install comfy-cli
comfy install

Linux/OSX:

python -m venv venv
. venv/bin/activate
pip install comfy-cli
comfy install

Installation[method4] (Installation for linux+venv: ComfyUI + ComfyUI-Manager)

To install ComfyUI with ComfyUI-Manager on Linux using a venv environment, you can follow these steps:

• prerequisite: python-is-python3, python3-venv, git

1. Download scripts/install-comfyui-venv-linux.sh into empty install directory

• ComfyUI will be installed in the subdirectory of the specified directory, and the directory will contain the generated executable script.

2. chmod +x install-comfyui-venv-linux.sh
3. ./install-comfyui-venv-linux.sh

Installation Precautions

• DO: ComfyUI-Manager files must be accurately located in the path ComfyUI/custom_nodes/ComfyUI-Manager
  • Installing in a compressed file format is not recommended.
• DON'T: Decompress directly into the ComfyUI/custom_nodes location, resulting in the Manager contents like __init__.py being placed directly in that directory.
  • You have to remove all ComfyUI-Manager files from ComfyUI/custom_nodes
• DON'T: In a form where decompression occurs in a path such as ComfyUI/custom_nodes/ComfyUI-Manager/ComfyUI-Manager.
  • You have to move ComfyUI/custom_nodes/ComfyUI-Manager/ComfyUI-Manager to ComfyUI/custom_nodes/ComfyUI-Manager
• DON'T: In a form where decompression occurs in a path such as ComfyUI/custom_nodes/ComfyUI-Manager-main.
  • In such cases, ComfyUI-Manager may operate, but it won't be recognized within ComfyUI-Manager, and updates cannot be performed. It also poses the risk of duplicate installations.
  • You have to rename ComfyUI/custom_nodes/ComfyUI-Manager-main to ComfyUI/custom_nodes/ComfyUI-Manager

You can execute ComfyUI by running either ./run_gpu.sh or ./run_cpu.sh depending on your system configuration.

How To Use

1. Click "Manager" button on main menu

   

2. If you click on 'Install Custom Nodes' or 'Install Models', an installer dialog will open.

   

   • There are three DB modes: DB: Channel (1day cache), DB: Local, and DB: Channel (remote).

     • Channel (1day cache) utilizes Channel cache information with a validity period of one day to quickly display the list.
       • This information will be updated when there is no cache, when the cache expires, or when external information is retrieved through the Channel (remote).
       • Whenever you start ComfyUI anew, this mode is always set as the default mode.
     • Local uses information stored locally in ComfyUI-Manager.
       • This information will be updated only when you update ComfyUI-Manager.
       • For custom node developers, they should use this mode when registering their nodes in custom-node-list.json and testing them.
     • Channel (remote) retrieves information from the remote channel, always displaying the latest list.
     • In cases where retrieval is not possible due to network errors, it will forcibly use local information.

   • The Fetch Updates menu retrieves update data for custom nodes locally. Actual updates are applied by clicking the Update button in the Install Custom Nodes menu.

3. Click 'Install' or 'Try Install' button.

   

   

   • Installed: This item is already installed.

   • Install: Clicking this button will install the item.

   • Try Install: This is a custom node of which installation information cannot be confirmed. Click the button to try installing it.

   • If a red background Channel indicator appears at the top, it means it is not the default channel. Since the amount of information held is different from the default channel, many custom nodes may not appear in this channel state.

     • Channel settings have a broad impact, affecting not only the node list but also all functions like "Update all."

   • Conflicted Nodes with a yellow background show a list of nodes conflicting with other extensions in the respective extension. This issue needs to be addressed by the developer, and users should be aware that due to these conflicts, some nodes may not function correctly and may need to be installed accordingly.

4. If you set the Badge: item in the menu as Badge: Nickname, Badge: Nickname (hide built-in), Badge: #ID Nickname, Badge: #ID Nickname (hide built-in) the information badge will be displayed on the node.

   • When selecting (hide built-in), it hides the 🦊 icon, which signifies built-in nodes.
     • Nodes without any indication on the badge are custom nodes that Manager cannot recognize.
   • Badge: Nickname displays the nickname of custom nodes, while Badge: #ID Nickname also includes the internal ID of the node.

   

5. Share

• You can share the workflow by clicking the Share button at the bottom of the main menu or selecting Share Output from the Context Menu of the Image node.
• Currently, it supports sharing via https://comfyworkflows.com/, https://openart.ai, https://youml.com as well as through the Matrix channel.

• Through the Share settings in the Manager menu, you can configure the behavior of the Share button in the Main menu or Share Ouput button on Context Menu.
  • None: hide from Main menu
  • All: Show a dialog where the user can select a title for sharing.

Snapshot-Manager

• When you press Save snapshot or use Update All on Manager Menu, the current installation status snapshot is saved.
  • Snapshot file dir: ComfyUI-Manager/snapshots
  • You can rename snapshot file.
• Press the "Restore" button to revert to the installation status of the respective snapshot.
  • However, for custom nodes not managed by Git, snapshot support is incomplete.
• When you press Restore, it will take effect on the next ComfyUI startup.
  • The selected snapshot file is saved in ComfyUI-Manager/startup-scripts/restore-snapshot.json, and upon restarting ComfyUI, the snapshot is applied and then deleted.

cm-cli: command line tools for power user

• A tool is provided that allows you to use the features of ComfyUI-Manager without running ComfyUI.
• For more details, please refer to the cm-cli documentation.

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.

NODE_CLASS_MAPPINGS = {
    "ExecutionSwitch": ExecutionSwitch,
    "ExecutionBlocker": ExecutionBlocker,
    ...
}

NODE_CLASS_MAPPINGS.update({
    "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.

"""

• 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.

Component Sharing

• Copy & Paste

  • Demo Page
  • When pasting a component from the clipboard, it supports text in the following JSON format. (text/plain)

    {
      "kind": "ComfyUI Components",
      "timestamp": <current timestamp>,
      "components": 
        {
          <component name>: <component nodedata>
        }
    }
    

  • <current timestamp> Ensure that the timestamp is always unique.
    • "components" should have the same structure as the content of the file stored in ComfyUI-Manager/components.
      • <component name>: The name should be in the format <prefix>::<node name>.
        • <compnent nodeata>: In the nodedata of the group node.
          • <version>: Only two formats are allowed: major.minor.patch or major.minor. (e.g. 1.0, 2.2.1)
          • <datetime>: Saved time
          • <packname>: If the packname is not empty, the category becomes packname/workflow, and it is saved in the .pack file in ComfyUI-Manager/components.
          • <category>: If there is neither a category nor a packname, it is saved in the components category.

              "version":"1.0",
              "datetime": 1705390656516,
              "packname": "mypack",
              "category": "util/pipe",
          

• Drag & Drop

  • Dragging and dropping a .pack or .json file will add the corresponding components.
  • Example pack: Impact.pack

• Dragging and dropping or pasting a single component will add a node. However, when adding multiple components, nodes will not be added.

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.

Additional Feature

• Logging to file feature

  • This feature is enabled by default and can be disabled by setting file_logging = False in the config.ini.

• Fix node(recreate): When right-clicking on a node and selecting Fix node (recreate), you can recreate the node. The widget's values are reset, while the connections maintain those with the same names.

  • It is used to correct errors in nodes of old workflows created before, which are incompatible with the version changes of custom nodes.

• Double-Click Node Title: You can set the double click behavior of nodes in the ComfyUI-Manager menu.

  • Copy All Connections, Copy Input Connections: Double-clicking a node copies the connections of the nearest node.

    • This action targets the nearest node within a straight-line distance of 1000 pixels from the center of the node.
    • In the case of Copy All Connections, it duplicates existing outputs, but since it does not allow duplicate connections, the existing output connections of the original node are disconnected.
    • This feature copies only the input and output that match the names.

  • Possible Input Connections: It connects all outputs that match the closest type within the specified range.

    • This connection links to the closest outputs among the nodes located on the left side of the target node.

  • Possible(left) + Copy(right): When you Double-Click on the left half of the title, it operates as Possible Input Connections, and when you Double-Click on the right half, it operates as Copy All Connections.

• Prevent downgrade of specific packages

  • List the package names in the downgrade_blacklist section of the config.ini file, separating them with commas.
    • e.g

      downgrade_blacklist = diffusers, kornia
    

• Custom pip mapping

  • When you create the pip_overrides.json file, it changes the installation of specific pip packages to installations defined by the user.
    • Please refer to the pip_overrides.json.template file.

Scanner

When you run the scan.sh script:

• It updates the extension-node-map.json.

  • To do this, it pulls or clones the custom nodes listed in custom-node-list.json into ~/.tmp/default.
  • To skip this step, add the --skip-update option.
  • If you want to specify a different path instead of ~/.tmp/default, run python scanner.py [path] directly instead of scan.sh.

• It updates the github-stats.json.

  • This uses the GitHub API, so set your token with export GITHUB_TOKEN=your_token_here to avoid quickly reaching the rate limit and malfunctioning.
  • To skip this step, add the --skip-update-stat option.

• The --skip-all option applies both --skip-update and --skip-stat-update.

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.
• If you encounter the error message Overlapped Object has pending operation at deallocation on Comfyui Manager load under Windows
  • Edit config.ini file: add windows_selector_event_loop_policy = True

Security policy
