## What it is
EmbedIO is a tiny, cross-platform, module-based web server library for .NET Framework and .NET Core, written entirely in C#. It supports REST APIs, static/embedded file serving, WebSockets, CORS, sessions, and SSL with a small memory footprint.

## Use cases
- embed a web server in a .NET desktop application
- serve a React or Angular SPA from a C# app
- build a small REST API in .NET without IIS or Kestrel
- serve static or embedded files with minimal code
- add WebSocket support to a .NET application
- run a web server on Raspberry Pi with Mono
- create a cross-platform GUI backend using web technologies

## When to choose
- you need a lightweight embedded HTTP server inside a .NET application
- you want cross-platform support including Mono and Raspberry Pi
- you need quick REST API or static file serving with minimal setup

## When to avoid
- you need a full-featured, high-performance production web server like ASP.NET Core Kestrel
- you require extensive middleware ecosystem and enterprise-grade features
- your project is not on the .NET platform

## Facets
- artifact type: library
- maturity: stable
- function: http-server, websocket, routing, middleware
- domain: web-development, backend, apis
- platform: dotnet, cross-platform, windows, embedded
- tags: embedded-web-server, rest-api, mono, raspberry-pi, static-files, cors, ssl, linux, macos
