## What it is
A Spring Boot starter that integrates the gRPC framework into Spring applications, auto-configuring gRPC servers for @GrpcService beans and managing channels/stubs for @GrpcClient annotations. It supports Spring Security and Spring Cloud service discovery (Consul, Eureka, Nacos).

## Use cases
- expose grpc services in a spring boot app
- inject grpc client stubs with annotations
- register grpc servers with eureka or consul
- secure grpc endpoints with spring security
- build microservices with grpc and spring cloud

## When to choose
- you use Spring Boot and want gRPC with minimal boilerplate
- you need gRPC service discovery via Spring Cloud
- you want annotation-driven gRPC server and client configuration

## When to avoid
- you don't use the Spring ecosystem
- you need non-JVM gRPC support
- you prefer plain grpc-java without Spring integration

## Facets
- artifact type: library

- function: rpc, middleware, api-framework
- domain: backend, microservices, apis, developer-tools
- platform: jvm
- tags: grpc, spring-boot-starter, spring-cloud, service-discovery, microservices, spring
