Installing ComfyUI – Step-by-Step
1. Download ComfyUI
First, download ComfyUI from its official GitHub page or use this direct link to download.
You’ll notice there’s a desktop app and a portable version available. For now, we recommend the portable version, as it's been widely used and trusted in the community for a longer time.
Look under the “Releases” section and download ComfyUI_windows_portable_nvidia.7z. Unzip the downloaded archive anywhere on your computer.
2. Install Git
Next, you’ll need to install Git. Here’s the Git download link.
Simply download the Standalone Installer and install it with the default settings — no need to change anything.
3. Set up the ComfyUI Manager
Now you’ll set up the ComfyUI Manager. This tool automatically detects which nodes are missing from a workflow, helps you find them, and installs the needed node packs.
On the website scroll down to “Installation”. We are using method2!
Just right click on “scripts/install-manager-for-portable-version.bat” and Save Link As… to save the file in the root of you ComfyUI_windows_portable directory.
Then run the file by double-clicking to install the ComfyUI Manager. If a Microsoft Defender window appears, you can run the script anyway by clicking on “More info” and then “Run Anyway”.
A command window will appear installing ComfyUI Manager!
4. Start ComfyUI
Start ComfyUI by running the run_nvidia_gpu file in the main folder.
The ComfyUI interface will automatically open in your web browser.
Congratulations, you now have ComfyUI with the ComfyUI Manager running! 🎉
5. Load a Workflow
To load a workflow in ComfyUI, simply drag the provided .json file into the browser window — the workflow will load automatically.
If you have a JPEG with embedded metadata, you can drag that in too — ComfyUI will load the workflow from the image metadata.
Every image created and saved with the Save Image node will include the workflow it was created with.
6. Install Missing Nodes
If some nodes are missing when you load a workflow, ComfyUI will display a message.
No worries: Simply open the ComfyUI Manager at the top of the interface and click "Install Missing Custom Nodes".
In the manager, you can select and install all missing nodes at once.
After downloading, you’ll need to restart ComfyUI so the new nodes can be loaded.
7. Add Models
Sometimes, you’ll need additional models. I’ll usually provide links to the models you need.
Once downloaded, place the models into the correct folders, as indicated in the workflow notes.
After placing the models into the correct folders, just press R in the ComfyUI interface to refresh the model list.
Now you’re ready to start working with our workflows in ComfyUI!
