Licensing
C6 Debugger uses serial key activation tied to a machine ID. Unregistered users can access Console and Debugger tabs with a 5-session limit.
Full activation unlocks all tools with no limits.
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.
License purchasing will be available soon.
