For community owners

Komm Server

Host your community on your own hardware. Channels, messages, voice rooms and permissions all live on your machine - database and media server are embedded, and the bundled launcher installs everything as a real OS service.

1 Create an account, then create an installation right from the Komm client - name it and pick your ports.

2 Run the Windows installer, or unpack the Linux package and run sudo ./install.sh. The launcher registers the server as a Windows Service or systemd unit.

3 Hand it the one-time verification code from the installation's card in the client. It fetches its certificate, verifies with the hub and comes online - kommserver update keeps it current.

Prefer to run things yourself? Grab the plain server JAR instead - it carries no verification code built in: drop your code into a setup-token.txt next to it and run it with Java 21. The launcher remains the recommended way - service install, crash recovery and automatic updates included.

Komm Hub

Run your own network. The hub manages accounts, friends and direct messages, and acts as the certificate authority that servers register with. Most people can simply use the official hub at kommvoice.com - but you don't have to.

Fair warning: the hub is aimed at developers. It needs a database, mail credentials and a local properties file - and the bundled website is this site, meant to be forked and personalized rather than used as-is. The setup guide covers everything.
