A powerful tool that translates ComfyUI workflows into executable Python code.
The ComfyUI-to-Python-Extension
is a powerful tool that translates ComfyUI workflows into executable Python code. Designed to bridge the gap between ComfyUI's visual interface and Python's programming environment, this script facilitates the seamless transition from design to code execution. Whether you're a data scientist, a software developer, or an AI enthusiast, this tool streamlines the process of implementing ComfyUI workflows in Python.

directory
Clone this repo
git clone https://github.com/pydn/ComfyUI-to-Python-Extension.git
After cloning the repo, your ComfyUI
directory should look like this:

requirements.txt
server.py
Navigate to the ComfyUI-to-Python-Extension
folder and install requirements
pip install -r requirements.txt
Launch ComfyUI, click the gear icon over Queue Prompt
, then check Enable Dev mode Options
. THE SCRIPT WILL NOT WORK IF YOU DO NOT ENABLE THIS OPTION!
Load up your favorite workflows, then click the newly enabled Save (API Format)
button under Queue Prompt
Move the downloaded .json workflow file to your ComfyUI/ComfyUI-to-Python-Extension
folder
If needed, update the input_file
and output_file
variables at the bottom of comfyui_to_python.py
to match the name of your .json workflow file and desired .py file name. By default, the script will look for a file called workflow_api.json
. You can also update the queue_size
variable to your desired number of images that you want to generate in a single script execution. By default, the scripts will generate 10 images.
Run the script:
python comfyui_to_python.py
After running comfyui_to_python.py
, a new .py file will be created in the current working directory. If you made no changes, look for workflow_api.py
.
Now you can execute the newly created .py file to generate images without launching a server.
