Additional platforms reserved for future use.
Connecting to a Private System
If your organization runs a licensed system, your administrator provides a QR code or server address. Open Server Management, scan or enter it, and the app verifies certificates — no account required.
Deploying a Server
Running your own server requires an operator license and documentation. Start with the operator documentation and for operators.
Requirements include Node.js 18+, Redis, and a System CA from your license workflow.
