rpcx is a high-performance distributed RPC framework for Go, comparable to Alibaba Dubbo but designed natively for Go without requiring proto/IDL files. It provides service discovery, load balancing, failover, circuit breaking, and pluggable transports (TCP, HTTP, QUIC, KCP, WebSocket, RDMA) with cross-language clients via gateway and Java/Rust implementations.

Use cases

• build microservices in Go with RPC instead of REST
• dubbo-like service governance framework for Go
• rpc framework without protobuf IDL definitions
• service discovery and load balancing for Go backends
• high-performance RPC alternative to grpc-go
• call Go services from Java or other languages
• broadcast and async RPC calls across service instances

When to choose

• you want Dubbo-style RPC with service discovery, failover, and circuit breaking in Go
• you prefer defining services as plain Go methods without writing proto files
• you need multiple transports like QUIC, KCP, or RDMA
• you need cross-language access via gateway, Java, or Rust clients

When to avoid

• your team is standardized on gRPC and needs its ecosystem and tooling
• you need browser-native clients without a gateway layer
• you require a license with guaranteed permissive terms (license file is non-standard)
• you only need simple HTTP/JSON APIs rather than binary RPC
