## What it is
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
