rpcx

rpcx is a Go RPC framework built for microservices, cloud systems, and high-performance distributed applications. It is positioned as an alternative to frameworks such as Dubbo and Motan, but with a Go-first development model. Developers can expose ordinary Go methods as remote services without defining proto files for every interface. The framework supports multiple transports, codecs, discovery backends, governance tools, and resiliency patterns. It includes features for failover, load balancing, compression, metadata, authorization, heartbeat checks, circuit breaking, and bidirectional communication. rpcx is useful for teams that want a flexible RPC layer with service discovery, gateway access, and extensibility built into the same ecosystem.
