## What it is
Crow is a fast, header-only C++ micro web framework inspired by Python Flask, offering Flask-like routing, built-in JSON handling, Mustache templating, middleware, and WebSocket support. This original repository is no longer maintained; development continues on the CrowCpp/Crow fork.

## Use cases
- build a REST API in C++
- serve JSON endpoints with a lightweight C++ web server
- create a small web backend without a heavy framework
- handle websockets in a C++ application
- render HTML pages with mustache templates in C++

## When to choose
- you want a Flask-like micro framework in C++
- you need a header-only web server with minimal setup
- you need fast routing and built-in JSON support in C++

## When to avoid
- you need an actively maintained project - use the CrowCpp/Crow fork instead
- you need a full-featured framework with built-in ORM
- your project requires long-term support and security updates

## Facets
- artifact type: framework
- maturity: abandoned
- function: web-framework, http-server, routing, templating, websocket, middleware, serialization
- domain: web-development, backend, apis
- platform: cpp, cross-platform, windows
