Asynchronous Component based Event Application Framework

Project description


circuits is a Lightweight Event driven and Asynchronous Application Framework for the Python Programming Language with a strong Component Architecture.

circuits also includes a lightweight, high performance and scalable HTTP/WSGI compliant web server as well as various I/O and Networking components.

To take full advantage of circuits and its architecture, circuits requires that your application be designed in terms of components and their interactions (events) with each other. An application written using the circuits application framework is maintainable, scalable and easy to develop.

circuits’ Loosely Coupled Component Architecture allows for a high level of Reuse and Scalability. Components are Componsable and much of the component library that circuits ships with are implemented as composed components.


  • event driven
  • concurrency support
  • component archiecture
  • asynchronous I/O components
  • no required external dependencies
  • full featured web framework (circuits.web)
  • coroutine based synchronization primitives



The simplest and recommended way to install circuits is with pip. You may install the latest stable release from PyPI with pip:

> pip install circuits

If you do not have pip, you may use easy_install:

> easy_install circuits

Alternatively, you may download the source package from the PyPi Page or the Downloads page on the Website; extract it and install using:

> python install
