Show HN: My D&D combat-tracker is finally online

https://topoftheround.com
1•kristophph•1h ago
This is a combat-tracker app for dungeon masters of Dungeons & Dragons 5e games. It can help with organizing the combat encounter by showing all participants of an encounter in a list with all needed info like monster statblocks, conditions, attacks, spells etc.

I tried to make it very easy to use by offering keyboard shortcuts for all important actions. I think it can be used by just keyboard alone. It also has a command-palette like MacOS or Alfred on linux (shortcut is "/") that lets you search for all important commands and even glossary entries.

There is a "Demo mode" that shows an example encounter and guides you through the basic functions. If anyone wants to check it out and tell me if this is understandable or if I need to add more/better tutorial steps? That would be great :)

It is build with javascrpit/typescript and uses Firebase/Firestore.

Any DMs on here that want to give this a try?
