CherryPy – Simple Python Web Framework

CherryPy is a mature, open source, minimalist, Python object-oriented web framework. It’s designed for rapid development of web applications.

The software allows developers to build web applications in much the same way they would build any other object-oriented Python program. This results in smaller source code developed in less time.

CherryPy has four API layers; the application layer, the environment layer, the extension layer, and the core layer.

Features include:

  • Easy to understand.
  • Reliable, HTTP/1.1-compliant, WSGI thread-pooled webserver. CherryPy supports the WSGI interface defined in PEP 333 as well as its updates in PEP 3333. Supports: Apache, IIS, lighttpd, mod_python, FastCGI, SCGI, and mod_wsgi.
  • Easy to run multiple HTTP servers (e.g. on multiple ports) at once.
  • A powerful configuration system for developers and deployers alike. CherryPy comes with a fine-grained configuration mechanism and settings can be set at various levels.
  • A flexible plugin system. CherryPy plugins hook into events within the server process — into server startup, server shutdown, server exiting, etc. — to run code that needs to be run when the server starts up or shuts down. CherryPy’s backbone consists of a bus system implementing a simple publish/subscribe messaging pattern.
  • Built-in tools for caching, encoding, sessions, authentication, static content, and many more. CherryPy implements a simple caching system as a pluggable Tool.
  • Swappable and customizable.
  • A complete test suite for core functionality and associated framework which can be used to test CherryPy applications.
  • Built-in profiling, coverage, and testing support.
  • A native mod_python adapter.
  • External library, ws4py, supports WebSocket.
  • Architecture makes it easy to integrate common database interfaces such as the DB-API specified in PEP 249, and HTML templates such as Mako and Jinja2.
  • Helper class to ease writing functional tests.
  • Runs on Python 2.7+, 3.4+, PyPy, Jython and Android.
