About
What it does
40K Playbook is a free, fan-made companion for Warhammer 40,000, supporting both 10th and 11th edition. It turns your army roster into a step-by-step Playbook so you never miss an ability, stratagem window, buff, or transport rule mid-game.
Community

Data & attribution
Rules data comes from the Wahapedia data export, a set of files Wahapedia publishes for tools like this one to use. It is converted into the Playbook’s own format ahead of time, so the app never calls Wahapedia while you play. Enormous thanks to the Wahapedia team for maintaining it. The definitions used to read those files were adapted from the MIT-licensed depot project. Your own data is covered by the privacy notice.
Legal
This is an unofficial fan project, not affiliated with, endorsed by, or sponsored by Games Workshop. Warhammer 40,000 and all associated names, marks, and images are the intellectual property of Games Workshop Limited. This tool is free, carries no advertising, and exists to help people play the tabletop game they already own. If you are a rights holder with concerns, please get in touch on Discord and I will respond promptly.
Accuracy
Phase timing for unit abilities is worked out automatically from the rules text, so it is occasionally imperfect — anything that can’t be timed confidently is shown under “Always in effect” rather than hidden. Points and rules also change with Games Workshop’s balance updates, so a value here can lag the official app until the data is refreshed. The printed rules are authoritative; when in doubt, check your codex. Spotted something wrong? Report it in #bug-reports.
