Broadcast overlay control for live card breaks — multiple channels, one server.
Create a channel
Each channel is a fully independent board + randomizer + control panel —
run one channel per simultaneous stream. Sessions save automatically and survive
refreshes and server restarts.
Backup
The backup file contains every channel (marks, usernames, history,
settings, chases) and every saved preset list. Download one before each update.
Restore merges — it never deletes anything that isn't in the file.
