## What it is
SOFARPC is a high-performance, highly extensible, production-grade Java RPC framework developed and battle-tested at Ant Financial for over a decade. It simplifies point-to-point remote service invocation with no code intrusion and offers rich extensibility for filters, routing, load balancing, and service governance.

## Use cases
- make remote procedure calls between Java microservices
- build a service mesh-free microservice architecture in Java
- replace Dubbo with a lightweight Java RPC framework
- implement service load balancing and failover in Java
- expose and consume services over multiple protocols like Bolt, REST, and HTTP2
- integrate RPC with service registries like ZooKeeper or Nacos

## When to choose
- you need a mature, production-proven Java RPC framework with long-term enterprise use
- you want pluggable extensibility for routing, load balancing, and filters
- you need multi-protocol support (Bolt, REST, HTTP2, protobuf, hessian) in one framework
- you are building microservices on the SOFAStack ecosystem or SOFABoot

## When to avoid
- your services are polyglot and need first-class non-JVM client support
- you want a minimal RPC layer without a large framework surface
- your team is not on the JVM / Java stack
- you need gRPC-native interoperability as the primary protocol

## Facets
- artifact type: framework
- maturity: stable
- function: rpc, microservices, serialization, middleware
- domain: microservices, backend, developer-tools
- platform: jvm, cross-platform
- tags: java-rpc, service-governance, sofastack, bolt-protocol, service-registry, load-balancing, fault-tolerance
