## What it is
libhv is a cross-platform C/C++ network library providing an event loop with non-blocking IO and timers, similar to libevent/libuv but with a simpler API and richer built-in protocols. It supports TCP/UDP/SSL client and server development plus HTTP, WebSocket, MQTT, and Redis clients/servers.

## Use cases
- build a high-performance HTTP server in C++
- write a WebSocket client or server in C
- develop TCP/UDP client and server applications with an event loop
- create an MQTT client for IoT devices
- make HTTP requests from C++ like curl or python requests
- build a RESTful API service with routing and middleware
- implement a reverse or forward proxy server

## When to choose
- you want a simpler API than libevent/libuv/asio for network programming
- you need multiple protocols (HTTP, WebSocket, MQTT, Redis) in one lightweight C/C++ library
- you need cross-platform support including mobile (Android/iOS)
- you are building IoT or embedded network services in C/C++

## When to avoid
- you are working in a higher-level language like Python, Go, or Node.js
- you need an extremely battle-tested ecosystem with large community support like libuv or asio
- you only need a full-featured production web server rather than a library to build one
- you need HTTP/3 or QUIC support
