Setup

ComfyUI Setup

There are several ways to run ComfyUI in a local environment.

Portable Version (Recommended)
Desktop Version (Installer format)
Manual Installation Version (venv + Git / For advanced users)

The portable version is flexible yet stable, and since anyone can create a similar environment, this site will explain assuming that you are basically using the portable version.

In addition, let's install ComfyUI Manager here as well.

This is a tool that makes managing ComfyUI easy, such as installing custom nodes.

Setup with Portable Version

The portable version includes Python, PyTorch, and the CUDA environment, and works just by extracting it.

1. Download

Access the GitHub release page of ComfyUI and select the file that matches your GPU.

GPU Type	File Name (Example)	Remarks
NVIDIA GPU	`ComfyUI_windows_portable_nvidia.7z`	In an environment where the driver is new enough, please choose the standard one first. If startup fails, update the GPU driver or use the version for old drivers below.
NVIDIA GPU (Stable/Older environment)	`cu126`/`cu128`	Use this if you do not want to update the driver, or if the standard version terminates immediately after startup.
AMD GPU	`ComfyUI_windows_portable_amd.7z`	For AMD users.

2. Extract and Run

1. Right-click the downloaded 7z file and extract it with Extract All.
- As explained in Recommended Specs - Storage, we recommend placing it on an SSD.
1. Double-click run_nvidia_gpu.bat in the extracted folder to start it.
1. Initial startup takes time for environment configuration. If the browser opens automatically, it is successful.

3. Installing ComfyUI Manager

1. Install Git
- Download the installer from Git for Windows and install it.
- You can leave all settings as default (just keep clicking Next).

Open the installation location

Open the custom_nodes folder inside the ComfyUI folder.

📂ComfyUI_windows_portable/
└── 📂ComfyUI/
      └── 📂custom_nodes/

1. Open Terminal
- Type cmd in the address bar of the folder (where the path is displayed) and press the Enter key.
- A black screen (command prompt) will open.
1. Execute Command
- Copy the following command, paste it into the black screen (right click), and press the Enter key.
- ```
git clone https://github.com/ltdrdata/ComfyUI-Manager.git
```

If a folder named ComfyUI-Manager is created inside the custom_nodes folder, it is successful. Restart ComfyUI and a "Manager" button will be added to the menu.

Desktop Version

This is an installer format for Windows. It provides stable operation with ComfyUI Manager already installed, but there are slightly more restrictions.

Download

1. Download ComfyUI Setup.exe from the GitHub page of ComfyUI Desktop.
1. Run it and select the installation destination and GPU settings.

Manual Installation (Windows, Linux)

This is a standard installation method using git clone and pip.

About Python Version

Python 3.13 is recommended.
If issues occur with custom node dependencies, try 3.12.

1. Installation

First, clone the repository, create a virtual environment, and activate it.

# Clone the repository
git clone https://github.com/comfyanonymous/ComfyUI.git
cd ComfyUI

# Create and activate virtual environment (Windows)
python -m venv venv
venv\Scripts\activate

# (For Linux/macOS)
# python -m venv venv
# . venv/bin/activate

2. Install PyTorch (NVIDIA)

Stable:

pip install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu130

Nightly (Potential performance improvement):

pip install --pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/cu130

3. Install Dependencies

Execute the following inside the ComfyUI folder.

pip install -r requirements.txt

4. Installing ComfyUI Manager

Even with manual installation, Manager is essential.

cd custom_nodes
git clone https://github.com/ltdrdata/ComfyUI-Manager.git
cd ..

About Easy Installers

Easy installers like Pinokio and Stability Matrix are certainly convenient and allow you to easily introduce complex functions.

However, the more elements involved in between, the more troubles increase... When a problem occurs, it becomes difficult to pinpoint the cause, and eventually, there are situations where beginners cannot handle it.

Since introducing ComfyUI, including the portable version, is not that difficult, we recommend doing it simply by the means provided by the official.
