Netick
What it is
Netick is a free, server-authoritative networking solution for building state-synchronized multiplayer games in Unity. It includes a full-game replay system and client-side prediction with reconciliation while retaining server authority. Developers can run servers and clients in the same Unity project, including multiple servers within one Unity instance. Its networking approach uses tick-aligned simulation, snapshot interpolation, delta compression, and an abstract transport layer. Netick says it adjusts to poor network conditions to maintain smooth gameplay. Pro features include Interest Management to reduce server load and bandwidth and help prevent wallhacks, plus Lag Compensation for authoritative hit detection. LiteNetLib is the default transport. Official integrations add Unity Transport options including UDP, WebSocket, Unity Relay, and links between WebGL and native clients; optional TLS and DTLS encryption are available through that integration. The EOS transport offers relays, lobby creation and discovery, NAT punchthrough, and relay fallback. Installation requires Unity Editor 2021 or later and uses Unity Package Manager with a Git URL. Supported platforms depend on transport.
