## What it is
Cinatra is a cross-platform, header-only, high-performance HTTP framework written in modern C++20, supporting HTTP 1.0/1.1, SSL, and WebSocket. It provides both a coroutine-based HTTP server and an HTTP(S) client with features like file upload/download, redirects, and proxy support.

## Use cases
- build a high-performance http server in c++
- create a file upload and download server
- make http requests from c++ with a coroutine-based client
- build a websocket or real-time message push server
- develop a rest api backend in modern c++
- build an https server with ssl support

## When to choose
- you need a header-only, dependency-light C++ HTTP framework
- you want C++20 coroutine-based async networking without callbacks
- you need top-tier HTTP server performance in C++
- you need cross-platform support (Linux, macOS, Windows)

## When to avoid
- your toolchain does not support C++20 coroutines
- you need a full-featured web framework with templating, ORM, and middleware ecosystems
- you prefer a non-header-only library with separate binaries

## Facets
- artifact type: framework
- maturity: active
- function: web-framework, http-server, http-client, websocket, file-upload, routing
- domain: web-development, backend, apis, developer-tools
- platform: windows, cpp, cross-platform
- tags: header-only, cpp20, coroutines, high-performance, ssl, http-framework, linux, macos
