ZypherLink

ZypherLink is a modern, open-source multiplayer framework for Unity, designed for low-latency, scalable, and secure real-time games. It consists of:

• SyncServer: A robust Node.js WebSocket backend for authoritative multiplayer logic, replay logging, anti-cheat, and more.
• SyncAPI: A robust API backend maded in ExpressJS for JWT-Auth, versions check and admin messages.
• ZeroPing: A Unity C# client example for rapid prototyping and integration with SyncServer using NativeWebSocket

ZypherLink still in progress but, if this doesn't recibes more popularity I can't update for new content, sorry. Oooorrrrr, you can pester me in my DM in discord: superstrella#0110
