We've recently added openATTIC to the Black Duck Open Hub. If you haven't heard about Open Hub (formerly known as "Ohloh.net"), here's how they describe themselves:

The Black Duck Open Hub (formerly Ohloh.net) is an online community and public directory of free and open source software (FOSS), offering analytics and search services for discovering, evaluating, tracking, and comparing open source code and projects. Open Hub Code Search is free code search engine indexing over 21,000,000,000 lines of open source code from projects on the Black Duck Open Hub.

The source code analysis performed by Open Hub revealed a few interesting insights:

In a Nutshell, openattic...

... has had 6,686 commits made by 14 contributors representing 28,094 lines of code

... is mostly written in Python with an average number of source code comments

... has a codebase with a long source history maintained by a large development team with increasing Y-O-Y commits

... took an estimated 7 years of effort (COCOMO model) starting with its first commit in January, 2011 ending with its most recent commit 4 days ago

The languages summary also shows some interesting turning points caused by refactoring or changes in the underlying technologies used, e.g. in September 2013, where the amount of JavaScript and CSS code was drastically reduced, while the amount of Python code increased. According to the developers, this might have been caused by the switch from one version of Ext JS to a newer version. Also, merge of the new Web UI code based on AngularJS has left a notable mark in the June/July 2015 time frame.

It will be interesting to follow the future development of the project via this tool!
