Crow is a fast, header-only C++ microframework for building HTTP and WebSocket web services, with Flask-style routing and type-safe handlers. It includes built-in JSON support, Mustache templating, and middleware support.
Use cases
- build a REST API in C++
- create a websocket server
- serve JSON endpoints with a lightweight C++ framework
- write a small web service without heavy dependencies
- add HTTP routing to a C++ application
- render HTML pages with mustache templates in C++
When to choose
- you want a Flask-like API in modern C++
- you need a fast, header-only HTTP server with no build step
- you need HTTP/1.1 and WebSocket support in one lightweight library
When to avoid
- you need HTTP/2 or mature async support
- you need a full-featured framework with ORM, auth, and sessions built in
- you are not working in C++11/14 or newer
