ComfyUI on another computer

ComfyUI runs on another computer in your network (a desktop with the graphics card, a home server), NodeWise Studio on this one.

Not tried yet on a real install: this page was checked against test servers that answer the way ComfyUI does.

#On the computer with ComfyUI

ComfyUI answers only on its own computer unless it is started with --listen, for example:

python main.py --listen 0.0.0.0

Then every computer on the network can reach it, and ComfyUI has no password of its own: anyone on the network can use it. Do this only on a network you trust.

#In NodeWise Studio

1. Settings ▸ Connection ▸ ComfyUI address: http://<address of that computer>:8188, for example http://192.168.1.50:8188. For another computer the http:// (or https://) must be written.
2. Check ComfyUI, then Save settings and Read now.

Plain http is allowed: the app sends no password or key to ComfyUI. The hint under the field says so; where the network is not yours, put ComfyUI behind https.

#When it does not answer

• "ComfyUI does not answer at …": ComfyUI is not running there, the port is different, it was started without --listen, or a firewall blocks the port.
• "No computer named … was found": write the address in numbers.
• An address that sends the app to a sign-in page (a proxy with a password) is refused: "The address sends the app to another page…".

All messages: Connection problems.
