Amazon GameLift Servers vs Mirror Networking

Amazon GameLift Servers is a paid service for deploying, operating, and scaling dedicated cloud servers for session-based multiplayer games. It supports managed EC2 fleets, managed container fleets, and Anywhere fleets using customer-managed resources. AWS says servers can run in 26 Regions and 9 Local Zones across five continents, with 99.99% availability, while autoscaling can launch thousands of servers and reduce unused capacity. FlexMatch matches up to 200 players using rules such as skill or latency. Enhanced DDoS Protection is enabled by default at no additional charge, and Player Gateway can hide server IP addresses through relays. Integrations include Unreal Engine, Unity, O3DE, C++, C#, Go, Pragma, Heroic Labs/Nakama, and AccelByte. Dashboards, logs, CloudWatch alarms, and telemetry integrations support operations. Player platforms include PC, PlayStation, Xbox, Nintendo, mobile, web, and AR/VR, with cross-play on shared servers. New AWS customers may use the Free Tier for up to 12 months, subject to limits. Managed container fleets run on Linux only.

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.
