Change Open WebUI Port

Change Open WebUI Port | Generated by AI

Home 2025.08

To change the port when running Open WebUI using the open-webui serve command (typically after installing via pip), use the --port flag followed by your desired port number. The default port is 8080.

Steps:

Ensure Open WebUI is installed:
```
pip install open-webui
```
Run the server on a different port (e.g., 3000):
```
open-webui serve --port 3000
```
- This will make the WebUI accessible at http://localhost:3000 (or your server’s IP address with the new port).
- Note: The PORT environment variable is ignored when using the serve command; you must use the --port flag instead.

If you’re using Docker instead of direct installation:

Set the PORT environment variable, e.g., docker run -e PORT=3000 ....
Map the port externally with -p <host_port>:3000 (adjust as needed).

For full installation and configuration details, refer to the official documentation.
