## What it is
RESTinio is a C++17 header-only library providing an embedded asynchronous HTTP(S)/WebSocket server built on standalone ASIO. It offers ExpressJS-like routing, middleware chaining, TLS, compression, and HTTP pipelining with a balance of performance and ease of use.

## Use cases
- embed an http server in a c++ application
- build a rest api in c++
- add websocket support to a c++ backend
- serve https with tls in a lightweight c++ server
- handle async http requests with pipelining
- implement express-style routing in c++

## When to choose
- you need an embedded, high-performance async HTTP/WebSocket server in C++
- you want ExpressJS-like routing and middleware in a C++17 codebase
- you need TLS, compression, and sendfile support without running a separate web server

## When to avoid
- you need a full-featured standalone web server with static config and process management
- your project is not C++ or cannot use ASIO
- you want a batteries-included framework with ORM, templating, and auth out of the box

## Facets
- artifact type: library
- maturity: stable
- function: http-server, websocket, routing, middleware, http-client
- domain: web-development, backend, apis
- platform: windows, cpp, cross-platform
- tags: header-only, asio, rest, tls, async, embedded-server, linux, macos
