C6 Debugger uses serial key activation tied to a machine ID. Unregistered users can access Console and Debugger tabs with a 5-session limit.

Cloud features (Cloud Sync and Tailscale integration) require a monthly subscription. This keeps your data encrypted and synced across devices, and enables remote connectivity through Tailscale.
