## What it is
Dyad.c is a lightweight, portable asynchronous networking library for C, distributed as just two source files. It supports building small TCP servers and clients with an event-listener API.

## Use cases
- write an async TCP server in C
- add networking to an existing C project
- build a simple echo server
- connect to a TCP service from C
- embed lightweight socket handling in a game or tool

## When to choose
- you need a tiny, dependency-free C networking layer
- you want event-driven TCP sockets that compile anywhere
- you prefer dropping two files into your project over pulling in libuv

## When to avoid
- you need high-performance, production-grade async I/O at scale
- you need TLS/SSL support out of the box
- you need UDP or higher-level protocols like HTTP

## Facets
- artifact type: library
- maturity: maintenance
- function: networking, http-server, websocket
- domain: networking, developer-tools, cross-platform
- platform: windows, cross-platform, c
- tags: async-networking, event-driven, sockets, single-file-library, tcp, linux, macos
