The independent community projects behind this Warhammer 40k hobby app — open catalogue data from BSData, rules references from Wahapedia, lore from the community wikis, and other hobby tools like GrimSlate.
This app is built on shared community projects: BSData and game-datacards for current-edition points, datasheets and stratagems, Wahapedia for the wider rules reference, and the Fandom and Lexicanum wikis for faction lore. It sits within a broader ecosystem of hobbyist tools, including list builders and battle trackers such as GrimSlate.
