ComfyUI Portable is a standalone packaged complete ComfyUI Windows version that has integrated an independent Python (python_embeded) required for ComfyUI to run. You only need to extract it to use it. Currently, the portable version supports running through Nvidia GPU or CPU.

This guide section will walk you through installing the corresponding software and generating your first image.

After downloading, you can use decompression software like 7-ZIP to extract the compressed package

The file structure and description after extracting the portable version are as follows:

ComfyUI_windows_portable
├── 📂ComfyUI                   // ComfyUI main program
├── 📂python_embeded            // Independent Python environment
├── 📂update                    // Batch scripts for upgrading portable version
├── README_VERY_IMPORTANT.txt   // ComfyUI Portable usage instructions in English
├── run_cpu.bat                 // Double click to start ComfyUI (CPU only)
└── run_nvidia_gpu.bat          // Double click to start ComfyUI (Nvidia GPU)

​
How to Start ComfyUI

Double click either run_nvidia_gpu.bat or run_cpu.bat depending on your computer’s configuration to start ComfyUI. You will see the command running as shown in the image below

When you see something similar to the image

To see the GUI go to: http://127.0.0.1:8188

At this point, your ComfyUI service has started. Normally, ComfyUI will automatically open your default browser and navigate to http://127.0.0.1:8188. If it doesn’t open automatically, please manually open your browser and visit this address.

During use, please do not close the corresponding command line window, otherwise ComfyUI will stop running

Additional ComfyUI Portable Instructions

​
1. Upgrading ComfyUI Portable

You can use the batch commands in the update folder to upgrade your ComfyUI Portable version

ComfyUI_windows_portable
└─ 📂update
   ├── update.py
   ├── update_comfyui.bat            // Update ComfyUI to the latest commit version
   ├── update_comfyui_and_python_dependencies.bat  // Only use when you have issues with your runtime environment
   └── update_comfyui_stable.bat     // Update ComfyUI to the latest stable version

​
2. ComfyUI Model Sharing and Custom Model Directory Configuration

If you are also using A1111 or want to customize your model storage location, you can modify the following file to complete the configuration

ComfyUI_windows_portable
└─ 📂ComfyUI
  └── extra_model_paths.yaml.example  // This file is the configuration template

Please copy or rename the extra_model_paths.yaml.example file in the corresponding folder to extra_model_paths.yaml

Below is the original configuration file content, which you can modify according to your needs

#Rename this to extra_model_paths.yaml and ComfyUI will load it


#config for a1111 ui
#all you have to do is change the base_path to where yours is installed
a111:
    base_path: path/to/stable-diffusion-webui/

    checkpoints: models/Stable-diffusion
    configs: models/Stable-diffusion
    vae: models/VAE
    loras: |
         models/Lora
         models/LyCORIS
    upscale_models: |
                  models/ESRGAN
                  models/RealESRGAN
                  models/SwinIR
    embeddings: embeddings
    hypernetworks: models/hypernetworks
    controlnet: models/ControlNet

#config for comfyui
#your base path should be either an existing comfy install or a central folder where you store all of your models, loras, etc.

#comfyui:
#     base_path: path/to/comfyui/
#     # You can use is_default to mark that these folders should be listed first, and used as the default dirs for eg downloads
#     #is_default: true
#     checkpoints: models/checkpoints/
#     clip: models/clip/
#     clip_vision: models/clip_vision/
#     configs: models/configs/
#     controlnet: models/controlnet/
#     diffusion_models: |
#                  models/diffusion_models
#                  models/unet
#     embeddings: models/embeddings/
#     loras: models/loras/
#     upscale_models: models/upscale_models/
#     vae: models/vae/

#other_ui:
#    base_path: path/to/ui
#    checkpoints: models/checkpoints
#    gligen: models/gligen
#    custom_nodes: path/custom_nodes

For example, if your WebUI is located at D://stable-diffusion-webui/, you can modify the corresponding configuration to

a111:
    base_path: D://stable-diffusion-webui/
    checkpoints: models/Stable-diffusion
    configs: models/Stable-diffusion
    vae: models/VAE
    loras: |
         models/Lora
         models/LyCORIS
    upscale_models: |
                  models/ESRGAN
                  models/RealESRGAN
                  models/SwinIR
    embeddings: embeddings
    hypernetworks: models/hypernetworks
    controlnet: models/ControlNet

This way, models under paths like D://stable-diffusion-webui/models/Stable-diffusion/ can be detected and used by ComfyUI Portable. Similarly, you can add other custom model location configurations

​
3. Setting Up LAN Access for ComfyUI Portable

If your ComfyUI is running on a local network and you want other devices to access ComfyUI, you can modify the run_nvidia_gpu.bat or run_cpu.bat file using Notepad to complete the configuration. This is mainly done by adding --listen to specify the listening address. Below is an example of the run_nvidia_gpu.bat file command with the --listen parameter added

.\python_embeded\python.exe -s ComfyUI\main.py --listen --windows-standalone-build
pause

After enabling ComfyUI, you will notice the final running address will become

Starting server

To see the GUI go to: http://0.0.0.0:8188
To see the GUI go to: http://[::]:8188

You can press WIN + R and type cmd to open the command prompt, then enter ipconfig to view your local IP address. Other devices can then access ComfyUI by entering http://your-local-IP:8188 in their browser
