LiteNetLib
LiteNetLib is a free, MIT-licensed UDP networking library for .NET Standard 2.1, Mono and .NET.
What LiteNetLib is
LiteNetLib is a free, MIT-licensed UDP networking library for .NET Standard 2.1, Mono and .NET. It supports peer-to-peer connections and multiple data channels, with reliable, ordered, sequenced and unreliable packet delivery. Packet tools include automatic merging, reliable fragmentation, MTU detection and a fast serializer. Other features include UDP NAT hole punching, NTP time requests, IPv6, multicasting, connection statistics, and packet loss and latency simulation; CRC32C checksums are optional. The project lists support for Unity, MonoGame, Godot and Lumin OS (Magic Leap), and links LiteEntitySystem as a higher-level API project. Targets include Windows, Mac, Linux, Android, iOS and Switch, as well as Unity desktop. Unity projects need version 2021.2 or later; the project recommends source or its OpenUPM package rather than precompiled DLLs. The library is available through NuGet, release builds and a DLL built from the master branch, which may be unstable. The README links Matrix chat for support.
