About

Happy Dwarf is a small volunteer team. We name our tools after the forge because we like work that is made slowly and meant to last, and because a dwarf without a hammer is just a short man with a beard.

Never touch the game’s files: No changes to eu4.exe, and Steam file checks keep working.
Open source, MIT, free: No payments and no data collection.
Claims we can back up: Measurements are labelled with their source; unverified things are marked as unverified.
