## What it is
Yar is a lightweight, concurrent RPC framework implemented as a native PHP extension (written in C), supporting HTTP, HTTPS, and TCP transports with pluggable packagers (PHP, JSON, Msgpack). It enables fast RPC communication between PHP applications and cross-language interop with C, Java, and Lua Yar implementations.

## Use cases
- call remote PHP services over RPC
- make multiple RPC calls concurrently from PHP
- build internal microservice communication between PHP apps
- serialize RPC payloads with msgpack or
- expose PHP services callable from C, Java, or Lua clients

## When to choose
- you need low-latency RPC between PHP applications with minimal setup
- you want concurrent parallel RPC calls from PHP
- you prefer a native extension over Composer-based userland libraries
- you need cross-language RPC with PHP, C, Java, or Lua

## When to avoid
- you need public-facing APIs for arbitrary third-party clients
- you require built-in service discovery, load balancing, or streaming
- you need schema-driven code generation like gRPC with Protobuf

## Facets
- artifact type: library
- maturity: stable
- function: rpc, serialization, concurrency
- domain: backend, apis, microservices, web-development
- platform: php, c, windows, cross-platform
