About Me

An indie developer. A long-time Shadowrun fan.

I built the tool I wanted at my own table.

I’m a long-time Shadowrun fan and an indie developer working as Chummer.Dev. During sessions I kept checking my character sheet to look up the dice pools I roll most often. So I built Chummer Kit: you set those pools up once and keep playing instead of digging through your sheet.

Gameplay comes first.

Every gameplay feature is free and always will be. The only optional purchases are cosmetic dice styles, cosmetic themes and a voluntary support purchase in the in-app shop. Support purchases simply support my work and don’t unlock any additional features.

If you’d like to help in another way, you can buy Shadowrun rulebooks from the Catalyst Game Labs store through the affiliate links in the app. I may earn a commission from qualifying purchases. The app identifies affiliate links before you follow them.

Fan-made. Independent.

Chummer Kit is an unofficial, fan-made app. It is not developed, published, sponsored or endorsed by Catalyst Game Labs or the owners of Shadowrun, and participation in the affiliate program does not change that.

Shadowrun, Catalyst Game Labs and other referenced names and trademarks belong to their respective owners. No ownership of those properties is claimed. Chummer Kit is a companion tool, not a replacement for the official rulebooks.
