## What it is
Haywire is an asynchronous HTTP server framework written in C, built on the libuv event loop that powers node.js. It aims for a minimal feature set with extremely high request throughput and low latency and resource usage.

## Use cases
- build a high-performance HTTP server in C
- serve millions of requests per second with low latency
- learn how to write an event-loop based HTTP server
- benchmark HTTP server throughput and latency
- build a minimal non-blocking web server on libuv

## When to choose
- you need maximum HTTP throughput and minimal latency in C
- you want a lightweight libuv-based server framework
- you are experimenting with or learning high-performance server internals

## When to avoid
- you need a full-featured web framework with routing, middleware, and ecosystem
- you want a maintained project with active development
- you prefer higher-level languages or batteries-included HTTP servers

## Facets
- artifact type: framework
- maturity: maintenance
- function: http-server, web-framework, concurrency, networking
- domain: web-development, backend, performance, developer-tools
- platform: windows, cross-platform, c
- tags: libuv, asynchronous-io, high-performance, http-keep-alive, http-pipelining, low-latency, linux, macos
