## What it is
ARPC is a high-performance RPC framework for Go supporting two-way calling, notify, broadcast, and pub/sub over TCP with customizable codecs and middleware. It emphasizes efficiency with features like singleflight call de-duplication, batch writes, and OpenTracing support.

## Use cases
- build a fast rpc server in go
- two-way communication between go services
- broadcast messages to connected clients
- pub/sub messaging in go
- replace grpc with a lighter rpc library
- async and sync remote calls with middleware

## When to choose
- you need bidirectional rpc or notify/broadcast patterns in Go
- you want a lightweight, high-throughput alternative to gRPC
- you need pub/sub or singleflight de-duplication built into your rpc layer

## When to avoid
- you need cross-language rpc with mature ecosystem support
- you require grpc-compatible protobuf contracts or http/2 transport
- your team needs long-term commercial-grade support guarantees

## Facets
- artifact type: library
- maturity: active
- function: rpc, middleware, serialization, websocket
- domain: microservices, networking, backend, developer-tools
- platform: go, windows, cross-platform
- tags: rpc-framework, two-way-communication, pub-sub, broadcast, singleflight, high-performance, linux, macos
