CherryPy is an object-oriented web application framework using the Python programming language. It is designed for rapid development of web applications by wrapping the HTTP protocol but stays at a low level and does not offer much more than what is defined in RFC 2616.

CherryPy can be a web server itself or one can launch it via any WSGI compatible environment (including Apache 2). It does not deal with tasks such as templating for output rendering, backend access, authentication protocols. The framework is extensible with filters, simple interfaces made of seven functions. These are called at defined points in the request/response processing.
