A sugar-free budget calculator, inspired by YNAB concept of managing personal finance. It is built on Rails, and intended to run on local machine. Or on a micro VPS instance like one you can rent on DigitalOcean for $5.
At the moment I have no intention to raise a public service or a distributable product. I’ve built this application for myself, and there are no any kind of installation guides here. You need some Ruby experience to run it :) Brew and powder may help on OS X.
And there’s also a demo instance on Heroku. Happy hacking!
