Mirror Networking vs yojimbo

Mirror Networking is a free system for adding multiplayer capabilities to Unity games. It uses a server-authoritative model by default and supports dedicated servers as well as client hosts. Core tools include message handlers, serialization, distributed object management, and state synchronization. Unity components such as NetworkManager, NetworkIdentity, and NetworkBehaviour connect game objects and scripts, with automatic synchronization for transforms and script variables. Built-in transport choices include KCP UDP, Telepathy TCP, WebSockets, a multiplexer, latency simulation, encryption, and Edgegap Relay. Other transport connections include Steam, Epic Online Services, LiteNetLib, and ENet. Mirror is MIT licensed, with no paywalls or CCU costs. The maker says it stores no user data and performs no tracking, analytics, or advertising. Its feature list marks lag compensation and encryption as Beta, unreliable sync mode as in development, and bitpacking and prediction as being researched. The GitHub README recommends Unity 2019, 2020, 2021, 2022 LTS, or 6000.1 to get started.
