Bring the group to your own server

The app is only half of CVB. Run a server for your crew in about five minutes - your users, your channels, your invites. Nothing about your server touches the CVB master except release updates, and those are opt-in with one-click rollback. Your friends’ apps keep updating only from the signed master, so a self-hosted server can never push code to them.

Linux (Docker)

curl -o docker-compose.yml https://cvb.doinksndubstep.com/hub/install/docker-compose.yml
CVB_ANNOUNCED_ADDRESS=voice.example.com docker compose up -d

First boot prints a generated admin password. Open TCP 4443 + UDP 10000–10499 and you’re live.

Windows

Checks Node/ffmpeg/yt-dlp, generates credentials, registers a boot task, opens the firewall.
