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. This guide section will walk you through installing ComfyUI Portable.

​
Download ComfyUI Portable

Choose the download package that matches your GPU type. ComfyUI Portable provides separate packages for different GPU hardware.

​
Standard portable for Nvidia GPUs

Nvidia GPU (CUDA 13.0, Python 3.13)

For modern Nvidia GPUs (RTX series)

Nvidia GPU (CUDA 12.6, Python 3.12)

For Nvidia 10 series and older GPUs
Download the file and extract it with 7-ZIP. The extracted folder structure:
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)
Double click run_nvidia_gpu.bat to launch ComfyUI.
After downloading and extracting, you will see the command running as shown in the image below ComfyUI Portable Command Prompt 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

​
Adding Extra Model Paths

If you want to manage your model files outside of ComfyUI/models, you may have the following reasons:
  • You have multiple ComfyUI instances and want them to share model files to save disk space
  • You have different types of GUI programs (such as WebUI) and want them to use the same model files
  • Model files cannot be recognized or found
We provide a way to add extra model search paths via the extra_model_paths.yaml configuration file

​
Open Config File

For the ComfyUI version such as portable and manual, you can find an example file named extra_model_paths.yaml.example in the root directory of ComfyUI:
ComfyUI/extra_model_paths.yaml.example
Copy and rename it to extra_model_paths.yaml for use. Keep it in ComfyUI’s root directory at ComfyUI/extra_model_paths.yaml. You can also find the config example file here
If the file does not exist, you can create it yourself with any text editor.

​
Example Structure

Suppose you want to add the following model paths to ComfyUI: 
📁 YOUR_PATH/
  ├── 📁models/
  |   ├── 📁 loras/
  |   │   └── xxxxx.safetensors
  |   ├── 📁 checkpoints/
  |   │   └── xxxxx.safetensors
  |   ├── 📁 vae/
  |   │   └── xxxxx.safetensors
  |   └── 📁 controlnet/
  |       └── xxxxx.safetensors
Then you can configure the extra_model_paths.yaml file like below to let ComfyUI recognize the model paths on your device: 
my_custom_config:
    base_path: YOUR_PATH
    loras: models/loras/
    checkpoints: models/checkpoints/
    vae: models/vae/
    controlnet: models/controlnet/
or 
my_custom_config:
    base_path: YOUR_PATH/models/
    loras: loras
    checkpoints: checkpoints
    vae: vae
    controlnet: controlnet
For the desktop version, please add the configuration to the existing configuration path without overwriting the path configuration generated during installation. Please back up the corresponding file before modification, so that you can restore it when you make a mistake.
Or you can refer to the default extra_model_paths.yaml.example for more configuration options. After saving, you need to restart ComfyUI for the changes to take effect. Below is the original config example: 
#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

​
Add Extra Custom Nodes Path

Besides adding external models, you can also add custom nodes paths that are not in the default path of ComfyUI
Please note that this will not change the default installation path of custom nodes, but will add an extra path search when starting ComfyUI. You still need to complete the installation of custom node dependencies in the corresponding environment to ensure the integrity of the running environment.
Below is a simple configuration example (MacOS), please modify it according to your actual situation and add it to the corresponding configuration file, save it and restart ComfyUI for the changes to take effect: 
my_custom_nodes:
  custom_nodes: /Users/your_username/Documents/extra_custom_nodes

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. 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 corresponding .bat file (e.g. run_nvidia_gpu.bat, run_amd_gpu.bat, or run_cpu.bat) 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.
