As part of the ongoing dogfooding campaign, we just migrated our issue tracker from an internal server to PythonAnywhere. Am happy to say it runs faster!
We use Trac, a python-based PM tool. Here's a brief outline, in case anyone else wants to host a trac site using PythonAnywhere.
And, optionally, use MySql as your database, although it's not recommended!
Need more info? Did you try it yourself? Got any thoughts on htdigest vs other types of auth? Leave a comment!
