Amazon GameLift Servers vs FishNet

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.

FishNet is a networking solution for Unity games using a client-server model and a server-authoritative design. It supports dedicated servers, while developers can also run a server and client together for development and testing. Users may choose a host, including self-hosting or player-hosted servers, and the free plan has no CCU caps or paywalls. Its high-level API synchronizes state, logic, and objects; events and inheritance provide lower-level functionality. Built-in client-side prediction includes desynchronization smoothing and Rigidbody prediction, and Addressables support covers network scenes and prefabs. Other listed tools include buffered remote calls, area-of-interest controls, configurable SyncTypes, tick-based timing, and broadcasts. Customizable authenticators can require client authentication before server communication. Communication is unencrypted by default; FishyUnityTransport can enable DTLS for UDP or TLS for WebSocket. FishNet costs nothing. FishNet Pro costs $50, paid once and adds lag compensation and automatic removal of sensitive server logic from client builds. The documentation says prediction collider components currently support primitive shapes such as boxes, spheres, and circles.
