Usage

Installing ComfyUI

To install ComfyUI using comfy, simply run:

comfy install

This command will download and set up the latest version of ComfyUI and ComfyUI-Manager on your system. If you run in a ComfyUI repo that has already been setup. The command will simply update the comfy.yaml file to reflect the local setup

• comfy install --skip-manager: Install ComfyUI without ComfyUI-Manager.
• comfy --workspace=<path> install: Install ComfyUI into <path>/ComfyUI.
• For comfy install, if no path specification like --workspace, --recent, or --here is provided, it will be implicitly installed in <HOME>/comfy.

Specifying execution path

• You can specify the path of ComfyUI where the command will be applied through path indicators as follows:

  • comfy --workspace=<path>: Run from the ComfyUI installed in the specified workspace.
  • comfy --recent: Run from the recently executed or installed ComfyUI.
  • comfy --here: Run from the ComfyUI located in the current directory.

• --workspace, --recent, and --here options cannot be used simultaneously.

• If there is no path indicator, the following priority applies:

  • Run from the default ComfyUI at the path specified by comfy set-default <path>.
  • Run from the recently executed or installed ComfyUI.
  • Run from the ComfyUI located in the current directory.

• Example 1: To run the recently executed ComfyUI:

  • comfy --recent launch

• Example 2: To install a package on the ComfyUI in the current directory:

  • comfy --here node install ComfyUI-Impact-Pack

• Example 3: To update the automatically selected path of ComfyUI and custom nodes based on priority:

  • comfy node update all

• You can use the comfy which command to check the path of the target workspace.

  • e.g comfy --recent which, comfy --here which, comfy which, ...

Default Setup

The default sets the option that will be executed by default when no specific workspace's ComfyUI has been set for the command.

comfy set-default <workspace path> ?[--launch-extras="<extra args>"]

• --launch-extras option specifies extra args that are applied only during launch by default. However, if extras are specified at the time of launch, this setting is ignored.

Launch ComfyUI

Comfy provides commands that allow you to easily run the installed ComfyUI.

comfy launch

• To run with default ComfyUI options:

  comfy launch -- <extra args...>

  comfy launch -- --cpu --listen 0.0.0.0

  • When you manually configure the extra options, the extras set by set-default will be overridden.

• To run background

  comfy launch --background

  comfy --workspace=~/comfy launch --background -- --listen 10.0.0.10 --port 8000

  • Instances launched with --background are displayed in the "Background ComfyUI" section of comfy env, providing management functionalities for a single background instance only.
  • Since "Comfy Server Running" in comfy env only shows the default port 8188, it doesn't display ComfyUI running on a different port.
  • Background-running ComfyUI can be stopped with comfy stop.

Managing Custom Nodes

comfy provides a convenient way to manage custom nodes for extending ComfyUI's functionality. Here are some examples:

• Show custom nodes' information:

comfy node [show|simple-show] [installed|enabled|not-installed|disabled|all|snapshot|snapshot-list]
                             ?[--channel <channel name>]
                             ?[--mode [remote|local|cache]]

• comfy node show all --channel recent

  comfy node simple-show installed

  comfy node update all

  comfy node install ComfyUI-Impact-Pack

• Managing snapshot:

  comfy node save-snapshot

  comfy node restore-snapshot <snapshot name>

• Install dependencies:

  comfy node install-deps --deps=<deps .json file>

  comfy node install-deps --workflow=<workflow .json/.png file>

• Generate deps:

  comfy node deps-in-workflow --workflow=<workflow .json/.png file> --output=<output deps .json file>

Bisect custom nodes

If you encounter bugs only with custom nodes enabled, and want to find out which custom node(s) causes the bug, the bisect tool can help you pinpoint the custom node that causes the issue.

• comfy node bisect start: Start a new bisect session with optional ComfyUI launch args. It automatically marks the starting state as bad, and takes all enabled nodes when the command executes as the test set.
• comfy node bisect good: Mark the current active set as good, indicating the problem is not within the test set.
• comfy node bisect bad: Mark the current active set as bad, indicating the problem is within the test set.
• comfy node bisect reset: Reset the current bisect session.

Managing Models

• Model downloading

  comfy model download --url <URL> ?[--relative-path <PATH>] ?[--set-civitai-api-token <TOKEN>]

  • URL: CivitAI, huggingface file url, ...

• Model remove

  comfy model remove ?[--relative-path <PATH>] --model-names <model names>

• Model list

  comfy model list ?[--relative-path <PATH>]

Managing ComfyUI-Manager

• disable GUI of ComfyUI-Manager (disable Manager menu and Server)

  comfy manager disable-gui

• enable GUI of ComfyUI-Manager

  comfy manager enable-gui

• Clear reserved startup action:

  comfy manager clear
