The tools
Free forever
Loonkostcalculator

Why it is free
Useful things, given freely.
These tools cost us next to nothing to run, so we keep them free and unlimited. If one of them saves you time and you want to say thanks, you can buy the team a coffee on Ko-fi. Totally optional, and never a wall.
Proxem is a digital architecture studio in Antwerp. If you need something bigger than a free tool, see what we build for clients.
