Albatross - a Toolkit for Stateful Web Applications

Introduction

Albatross is a small and flexible Python toolkit for developing highly stateful web applications. The toolkit has been designed to take a lot of the pain out of constructing intranet applications although you can also use Albatross for deploying publicly accessed web applications.

In slightly less than 2600 lines of Python (according to pycount), you get the following:

A primary design goal of Albatross is that it be small and easy to use and extend. The toolkit application functionality is defined by a collection of fine grained mixin classes. Eight different application types and four different execution contexts are prepackaged, allowing you to define your own drop in replacements for any of the mixins to alter any aspect of the toolkit semantics.

Object Craft developed Albatross because there was nothing available with the same capabilities which they could use for consulting work. For this reason the toolkit is important to Object Craft and so is actively maintained and developed.
