An open-source trading card collection manager that turns your physical binders into a searchable digital archive. Add a new binder, scan its pages, and OpenCV automatically detects each card on the page - with manual bounding box adjustments available whenever the auto-detection needs a nudge.
Each detected card is scored against everything you've already scanned, building two linked databases under the hood: a unique card database (one entry per distinct card) and a collection database (every copy you own and where it lives). Cards with confident similarity scores are auto-linked; ambiguous ones land in a review work queue where you confirm matches or flag them as new uniques.
Self-hosted with no cloud lock-in and no subscriptions - run it on your own hardware and own your data. Released free for the community as part of our commitment to open-source tools that help collectors and hobbyists keep their collections organized.
