## What it is
A full-featured Elixir implementation of the gRPC protocol supporting unary and streaming RPCs, interceptors, TLS, HTTP transcoding, and Protobuf code generation. It provides both client and server libraries for building gRPC services on the BEAM VM.

## Use cases
- build a gRPC server in Elixir
- call gRPC services from an Elixir client
- implement bidirectional streaming RPCs
- expose protobuf-defined APIs from a Phoenix/Elixir app
- add HTTP/JSON transcoding to a gRPC service
- use gRPC with TLS and interceptors on the BEAM

## When to choose
- you need gRPC client or server support in an Elixir or Erlang project
- you want streaming RPCs with a unified stream-based API
- you need HTTP transcoding or gRPC reflection in Elixir

## When to avoid
- your stack is not on the BEAM VM
- you only need simple REST APIs without protobuf
- you need first-party official gRPC tooling with broad language support

## Facets
- artifact type: library
- maturity: active
- function: rpc, http-server, http-client, serialization, middleware
- domain: apis, backend, web-development, developer-tools
- platform: elixir, jvm, windows
- tags: grpc, protobuf, http2, streaming, elixir, beam, tls, http-transcoding, interceptors, linux, macos
