Mirror Networking
The #1 free open source game networking library for Unity 2019 / 2020 / 2021 / 2022 LTS.
Used in production by major hits like Population: ONE and many more.
Originally based on UNET: battle tested since 2014 for 9 years and counting!
Mirror is stable, modular & easy to use for all types of games, even small MMORPGs 🎮.
Made in 🇩🇪🇺🇸🇬🇧🇸🇬🇹🇼 with ❤️.

Architecture
The Server & Client are ONE project in order to achieve maximum productivity.
Simply use NetworkBehaviour instead of MonoBehaviour.
Making multiplayer games this way is fun & easy:
public class Player : NetworkBehaviour
{
// Synced automatically
[SyncVar] public int health = 100;
// Lists, Dictionaries, Sets too
SyncList<Item> inventory = new SyncList<Item>();
// Server/Client-only code
[Server] void LevelUp() {}
[Client] void Animate() {}
void Update()
{
// isServer/isClient for runtime checks
if (isServer) Heal();
if (isClient) Move();
}
// Zero overhead remote calls
[Command] void CmdUseItem(int slot) {} // Client to Server
[ClientRpc] void RpcRespawn() {} // Server to all Clients
[TargetRpc] void Hello() {} // Server to one Client
}
There's also NetworkServer & NetworkClient.
And that's about it 🤩
