Komm Server

Host your community on your own hardware. Channels, messages, voice rooms and permissions all live on your machine — with an embedded database, there is nothing else to install.

1 Create an account and register your server from the dashboard.
2 Download the JAR pre-configured for your installation — certificates included.
