## What it is
Handy is a simple, easy-to-use C++11 network server library supporting high-concurrency TCP/UDP servers with epoll on Linux and kqueue on macOS. It offers concise APIs (a full echo server in ~10 lines), graceful shutdown, timers, SSL via OpenSSL, protobuf codecs, and half-sync/half-async processing.

## Use cases
- build a high-performance tcp server in c++
- handle millions of concurrent connections on one machine
- write a simple http server in c++
- build a udp server or client
- add ssl/tls to a c++ network server
- implement a half-sync half-async server
- learn epoll and kqueue event-driven programming

## When to choose
- you want a lightweight, minimal C++11 networking library with a small API surface
- you need very high concurrent connection counts on Linux
- you want epoll/kqueue examples to learn event-driven networking

## When to avoid
- you need a full-featured framework with async I/O across many platforms or Windows support
- you prefer mature, widely-adopted libraries like asio with large community support
- you need HTTP/2, WebSockets, or other advanced protocols out of the box

## Facets
- artifact type: library
- maturity: maintenance
- function: http-server, websocket, networking, concurrency, middleware
- domain: networking, backend, developer-tools, microservices
- platform: cpp, cross-platform
- tags: c++11, epoll, kqueue, tcp-server, udp, high-concurrency, event-driven, openssl, protobuf, linux, macos
