Changing the Client Frontend Port

Cider defaults to using port 9000 for the client frontend. If you need to change this port, you can do so by setting the PORT environment variable.

Note: This only works on Electron Clients. Setting the port on Sabiiro is currently not supported.

Setting the Port in the CLI

When running Cider from the CLI you can set the ports as follows:

PORT=1111 ./cider-2.4.1.appimage

This will start the client frontend on port 1111.

Setting the Port in a etc/environment File

In linux you can set the port in a etc/environment file. This file is read by the system on startup and sets the environment variables for all processes. MacOS users can use the ~/.bash_profile file.
