DM Hero is completely free and open source - and always will be. I develop it in my spare time because I'm passionate about D&D and helping fellow Dungeon Masters.
"Buy Me a Coffee" is a simple way to say thanks with a small donation. It helps cover hosting costs and motivates me to keep adding new features. No account needed, no subscription - just a one-time tip if you feel like it!
Every coffee fuels another late-night coding session. Thank you for your support!
