kegger
This is a simple counter for beer, sangria, cider and keggers as well other beverages. Although it can be changed to support any tipe of contable objects.
The purpose was to count how many beverages have been sold and served. This would give us the information if it would be lucrative to open another keg or not.
This is made free and open source under the AGPLv3 license.
Never used :(
