An IT knowledge base with real-time collaborative editing, edit locking and QR-code access.

The hardest part is the one nobody sees: a pessimistic edit lock on a 15-minute lease, so two technicians never write over each other. A lease rather than a permanent lock — if a browser dies, it expires on its own. Everything else arrives over SignalR, so what one person saves shows up for the others without a reload. Access is a token handed over as a QR code, with no password screen. One API serves the endpoints, the admin panel and the responsive web app. MIT licensed.
