About Atlantica Online Craft Calculator


I got tired of waiting for updated version of Atlantica Online Craft Calculator from Muwing and using spreadsheets in LibreOffice so I started this project on my own.


I created simple library in my favorite programming language Ruby. Then I added web front end in ruby web framework Padrino. This is mountable engine for Ruby on Rails – remake of Padrino application.

Source code is available at: https://github.com/jana4u/atlantica_online_craft_calculator_engine.

It is open source and released under the MIT license.


My name is Jana Dvořáková (Jana4U) and I work mostly as Ruby on Rails developer. Playing Atlantica Online is my hobby.

If you like this project, you can do some in-game donations to my character Racek on Delphi server, member of EliteGuardians guild, Abyss nation. ;-)

If you have any questions or suggestions how to improve calculator, feel free to contact me.
