How to Access ComfyUI from Local Network

There are two ways to access ComfyUI from your local network, depending on which version you are using:

Method 1: For ComfyUI Desktop Version

1. Open ComfyUI Desktop
2. Go to Settings -> Server Configuration
3. Find the “Network” section
4. Change “Listen Address” from 127.0.0.1 to 0.0.0.0
5. Keep the default port 8000 (or change it if needed)
6. Restart ComfyUI Desktop

After these steps, you can access ComfyUI from other devices on your local network using:

http://<host-ip-address>:8000

Replace <host-ip-address> with your computer’s local IP address (e.g., 192.168.1.100).

Method 2: For ComfyUI Portable Version

1. Locate your run_nvidia_gpu.bat file in the ComfyUI folder
2. Right-click and edit this file
3. Find the line that contains python main.py
4. Add the -listen parameter with value 0.0.0.0:

python main.py --listen 0.0.0.0

5. Save the file and restart ComfyUI

You can then access ComfyUI from other devices using the same URL format:

http://<host-ip-address>:8188

Note that the portable version uses port 8188 by default.
