## What it is
Sylar is a high-performance C++ server framework built around user-space coroutines (fibers) with modules for logging, configuration, threading, coroutine scheduling, IO scheduling via epoll, socket hooking, serialization, and HTTP/WebSocket/HTTPS servers. It also includes SMTP email, MySQL, SQLite3, Redis, Zookeeper, and a lightweight ORM, and is accompanied by a video tutorial series for building it from scratch.

## Use cases
- build a high-performance tcp server in c++
- learn how to write a coroutine-based server framework
- serve http and websocket endpoints from c++
- hook blocking socket apis to make them async
- serialize binary data with varint support
- write a web server with servlet-style routing in c++

## When to choose
- you want to study or learn coroutine-based server architecture in C++
- you need a self-contained C++ backend framework with http, websocket, and database modules on Linux
- you prefer synchronous-style code with async performance via socket hooks

## When to avoid
- you need a production framework with an active community, license, and long-term support
- you target platforms other than Linux
- you want a modern C++20 coroutine or cross-platform solution like asio or drogon
