Complete Comfy CLI User Guide

Comfy CLI is the official command-line tool provided by ComfyUI. It not only simplifies the ComfyUI installation process but also offers powerful management capabilities. This guide will comprehensively cover all features of Comfy CLI.

Basic Commands

Installation and Setup

# Install comfy-cli
pip install comfy-cli
 
# Enable command-line auto-completion
comfy --install-completion
 
# Install ComfyUI
comfy install
 
# Launch ComfyUI
comfy launch

Workspace Management

comfy-cli supports managing multiple ComfyUI workspaces, allowing you to maintain different ComfyUI environments simultaneously:

Basic Workspace Operations

# Check current workspace path
comfy which
 
# Set default workspace
comfy set-default /path/to/your/workspace
 
# Set default workspace with launch parameters
comfy set-default /path/to/your/workspace --launch-extras="--listen 0.0.0.0 --port 8080"

Executing Commands in Different Workspaces

1. Specify workspace:

# Launch ComfyUI in specified workspace
comfy --workspace=/path/to/workspace launch
 
# Install nodes in specified workspace
comfy --workspace=/path/to/workspace node install ComfyUI-Impact-Pack

2. Use recent workspace:

# Launch most recently used ComfyUI
comfy --recent launch
 
# Update nodes in recent workspace
comfy --recent node update all

3. Operate in current directory:

# Install nodes in current directory's ComfyUI
comfy --here node install ComfyUI-Impact-Pack
 
# Launch ComfyUI in current directory
comfy --here launch
 
# Check if current directory has ComfyUI
comfy --here which

Workspace Option Restrictions

Important Note: --workspace, --recent, and --here options cannot be used simultaneously.

Workspace Priority Rules

When you don’t explicitly specify a workspace, comfy-cli will automatically select based on the following priority:

  1. Default ComfyUI path specified via comfy set-default <path>
  2. Most recently executed or installed ComfyUI
  3. ComfyUI in the current directory

Practical Usage Examples

Scenario 1: Creating Independent Environments for Different Projects

# Create workspace for Project A
comfy --workspace=~/projects/projectA install
 
# Create workspace for Project B
comfy --workspace=~/projects/projectB install
 
# Install specific nodes in Project A
comfy --workspace=~/projects/projectA node install ComfyUI-AnimateDiff-Evolved
 
# Install different nodes in Project B
comfy --workspace=~/projects/projectB node install ComfyUI-Impact-Pack

Scenario 2: Quick Environment Switching

# Set frequently used workspace as default
comfy set-default ~/projects/main-workspace
 
# Temporarily work in another workspace
comfy --workspace=~/projects/test-workspace launch
 
# Return to default workspace
comfy launch
