Share one LEGO® collection with your whole household
In most homes, a LEGO® collection is not really one person's. Partners buy sets together, kids build them, and everyone wants to know what is owned, what is wanted, and what is half-finished on the dining table. The problem is that most tools were built for a single account, so families end up with two or three separate copies that drift apart, or one shared login that turns into a tug-of-war over who edited what.
Brickmaster takes a different approach. Household sharing gives you a single shared collection that everyone can see, with clear owner, editor, and viewer roles so the right people can change things and the rest can browse without breaking anything. Add a set on your phone in the LEGO® aisle and it is there on your partner's tablet at home, with offline sync that catches up the moment you reconnect.
One shared collection, not separate copies
The core idea is simple: your household has one collection, and every member sees the same Want, Ordered, Have, and Built status in real time. When your partner orders a set, it shows as Ordered for everyone. When a child finishes a build, the timer they ran updates the shared record. There is no exporting, re-importing, or asking each other what was already bought.
This is where a co-owned collection differs from a simple view-only share link. A share link lets someone look at one person's collection, which is great for showing it off, but it is not a collection that two or three people can both edit and own together. Household sharing is built for co-ownership, where each member has a real role instead of a read-only window into someone else's account.
- Owner: full control, including who is invited and what role they hold.
- Editor: can add, update, and check off sets, minifigures, and builds.
- Viewer: can browse the whole collection without changing anything, ideal for kids or relatives.
- Everyone shares the same source of truth, so there are no merge conflicts to untangle.
Built for families, partners, and kids
Roles make sharing safe across ages and households. Give a young builder a viewer seat so they can explore what is owned without accidentally deleting a set, or promote an older kid to editor so they can log their own builds. Partners can both be editors and keep one tidy shared library instead of two that disagree.
Because Brickmaster tracks LEGO® and alt-brick sets the same way, the whole household stays on one system regardless of which brands you collect. And the parts of Brickmaster people love most carry over to the shared view: the build tracker with a live timer and pieces-per-day velocity, minifigure tracking, and the sealed-box CMF scanner for collectible minifigures all reflect the shared collection, so a build your kid logs counts for the family, not just one login.
Offline sync that keeps everyone in step
LEGO® shopping and building rarely happen next to a perfect Wi-Fi signal. Brickmaster works offline and syncs automatically, so you can mark a set as Have in a store with a weak signal or check the shared list in the car, and it reconciles cleanly with everyone else's devices once you are back online. No duplicate entries, no overwriting your partner's changes.
Brickmaster runs on web, iOS, and Android, and command-K search spans 27,000+ sets across 490+ themes and 270+ colors, so finding the right set to add to the shared collection takes seconds. And with built-in CSV and JSON export, your shared household collection stays portable and never locked into one app.

Questions
Is Brickmaster affiliated with the LEGO Group?
No. Brickmaster is an independent app and is not affiliated with, authorized by, sponsored by, or endorsed by the LEGO Group. LEGO® is a trademark of the LEGO Group, and we use the name only to describe that Brickmaster helps you track LEGO® and alt-brick sets and minifigures.
How is household sharing different from sending someone a share link?
A view-only share link typically lets others look at one person's collection. Brickmaster household sharing instead gives you a single collection that multiple people co-own, with owner, editor, and viewer roles, so chosen members can actually add and update sets while others browse read-only. Everyone sees the same live status instead of separate copies that drift apart.
Will sharing cause sync conflicts between our devices?
No. Because the household shares one collection rather than separate copies, there is nothing to merge or reconcile by hand. Brickmaster works offline and syncs automatically, so changes from each member's phone, tablet, or browser come together cleanly the moment everyone is back online.
