CherryPy is a mature, production-grade Python web framework that maps HTTP requests to Python callables using an object-oriented approach. It provides a built-in HTTP server (via Cheroot), a flexible configuration system, a publish/subscribe bus for lifecycle management, and a rich middleware/tool system for authentication, sessions, caching, static file serving, and more. The architecture is modular: the core request/response pipeline, dispatchers (tree-walking, method-based, routes), and a plugin system allow deep customization. CherryPy can be used standalone or embedded in other WSGI servers. It is not a data research project; it is a pure application framework with extensive testing and documentation.
