MagicOnion is a unified RPC and real-time communication framework for .NET and Unity, built on gRPC and MessagePack. It uses C# interfaces as protocol schemas instead of .proto files, supporting both API services and bi-directional StreamingHub real-time communication.

Use cases

• build rpc services between .net microservices
• realtime multiplayer game server communication with unity
• replace wcf with a modern rpc framework
• bidirectional streaming like signalr or socket.io in c#
• share api contracts between c# client and server without proto files
• broadcast server data to multiple game clients

When to choose

• your entire stack is C#/.NET or Unity and you want schema-free code sharing
• you need both REST-like APIs and real-time streaming in one framework
• you're building Unity multiplayer games needing efficient binary transport

When to avoid

• you need cross-language clients (JavaScript, Python, etc.) since schemas are C# interfaces
• you already have .proto-based gRPC infrastructure
• you need plain HTTP/JSON APIs for third-party consumers
