BrickStore

BrickStore is an offline tool for managing BrickLink data across multiple platforms, including Windows, macOS, Linux, iOS and Android. It supports several languages—English, German, Spanish, Swedish and French—and is designed to be fast and stable, leveraging all CPU cores for quick operations.

The application lets users browse and search the BrickLink catalog with a live, as‑you‑type filter, generate XML files for mass‑upload or mass‑update of parts, and download or view orders and full inventory records. It also provides features for repricing using the latest price guide, fixing obsolete item IDs via the BrickLink catalog change‑log, and comparing two documents to assess build feasibility. Unlimited undo/redo and customizable printing through JavaScript templates are included.

BrickStore is released under the GNU GPL v3, with source code hosted on GitHub. It integrates third‑party components under various open‑source licenses and does not imply endorsement by BrickLink or LEGO.
