Open Source Web Frameworks in Python


Zope is an open source web application server primarily written in the Python programming language. It features a transactional object database which can store not only content and custom data, but also dynamic HTML templates, scripts, a search engine, and relational database (RDBMS) connections and code. It features a strong through-the-web development model, allowing you to update your web site from anywhere in the world. To allow for this, Zope also features a tightly integrated security model. Built around the concept of \"safe delegation of control\", Zope's security architecture also allows you to turn control over parts of a web site to other organizations or individuals. The transactional model applies not only to Zope's object database, but to many relational database connectors as well, allowing for strong data integrity. This transaction model happens automatically, ensuring that all data is successfully stored in connected data sources by the time a response is returned to a web browser or other client.

Webware for Python is a suite of Python packages and tools for developing object-oriented, web-based applications. The suite uses well known design patterns and includes a fast Application Server, Servlets, Python Server Pages (PSP), Object-Relational Mapping, Task Scheduling, Session Management, and many other features. Webware is very modular and easily extended.

Spyce is a server-side language that supports elegant and efficient Python-based dynamic HTML generation. Spyce allows embedding Python in pages similar to how JSP embeds Java, but Spyce is far more than a JSP clone. Out of the box, Spyce provides development as rapid as other modern frameworks like Rails, but with an cohesive design rather than a morass of special cases. Spyce's modular design makes it very flexible and extensible. It can also be used as a command-line utility for static text pre-processing or as a web-server proxy.

Maki is a webserving framework built on Python and XML. It allows a web developer to send an XML input document through any number of steps, where each step is either a stylesheet transformation or a custom process. A processor that evaluates embedded Python code is included. The output of each step is passed as the input to the next step (similar to a Unix pipe). Additionally, the output of each processor step can be cached for a user-specified time period. All configuration is done in XML files that allow you to specify rules based on matching paths against Unix-style wildcard patterns or regular expressions.

Karrigell is a flexible Python web framework, with a clear and intuitive syntax. It is independent from any database, ORM or templating engine, and lets the programmer choose between a variety of coding styles The package includes a powerful built-in web server, so there's no need to download, install and configure a separate one, and a pure-Python database engine, PyDbLite, which is used for the demos

Aquarium is a Web application framework, written in Python. It provides an approach to producing a Web application without duplication of effort by reducing the amount of code you need to write. It offers convenient libraries and extensible APIs for items such as session management and Web server integration (including CGI, mod_python, FastCGI, or its own Web server, Glass). It provides tight integration with Cheetah, including autocompilation of Cheetah templates.

Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design. Developed and used over two years by a fast-moving online-news operation, Django was designed to handle two challenges: the intensive deadlines of a newsroom and the stringent requirements of the experienced Web developers who wrote it. It lets you build high-performing, elegant Web applications quickly.

Go To Django is a web framework for python that is as simple as it is powerful. is in the public domain; you can use it for whatever purpose with absolutely no restrictions.

Pylons is a lightweight web framework emphasizing flexibility and rapid development. Pylons combines the very best ideas from the worlds of Ruby, Python and Perl, providing a structured but extremely flexible Python web framework. It's also one of the first projects to leverage the emerging WSGI standard, which allows extensive re-use and flexibility — but only if you need it. Out of the box, Pylons aims to make web development fast, flexible and easy.

Nevow (pronounced as the French \"nouveau\", or \"noo-voh\") is a web application construction kit written in Python. It is designed to allow the programmer to express as much of the view logic as desired in Python, and includes a pure Python XML expression syntax named stan to facilitate this. However it also provides rich support for designer-edited templates, using a very small XML attribute language to provide bi-directional template manipulation capability.

Turbogears is a high-level MVC based web framework for Python. It is built on top of a collection of best-of-breed WSGI components, like Pylons, SQLAlchemy, Repoze, and Genshi. However, there are numerous options and plugins available for whatever your coding preference may be. Speed, flexibility and simplicity are integral, as it is designed for rapid development without giving up on power.
