After using it I'll say it does what it says it would and does it well. It's nice and interactive and while it would make a nice local app, It's hardly suitable for a cli utility.
we will definitely add more formats. to decide which to start with we have the vote form on the homepage. so if you want django, please vote for it :)
Thought for your case we don't only need to add another format (more or less easy) but also support for re-uploading new designs .zip file, which is somewhat harder to implement and so is further down the todo list :)
it could be an open source rails application, of course, but so is a lot of other commercial projects out there :)
It is free for now and we don't plan on adding payments right away (and basics will probably stay free forever), but we do think about monetizing it some day.
For now though we are focused on creating something that people will like and use.
