Know what you own. Know what you can build. Know what it’s worth.
BrickzBack brings your LEGO collection, builds and value into one workspace. Track sets, minifigures and loose parts; plan projects using pieces you own; and follow value guidance alongside the work you do with your collection.
Updated . Values are guidance, photo matches need review, and you confirm collection changes.
What does BrickzBack help you do?
Keep owned sets, minifigures, loose pieces and wishlist items organised. Check a selected set or project against pieces marked available, see what remains, follow supported value guidance, and prepare editable Trader drafts from details you confirm.
Know what is in your collection
Track sets, minifigures and loose parts in one collection, with wishlist items kept separate. Part records include colour and quantity, so available pieces stay distinct from items already committed to a build or project.
When you identify an unfamiliar item, BrickVision can suggest likely matches from a photo of a part, set or figure. Review the candidate and confirm it yourself; a suggestion does not add anything to your collection.
Plan a set recovery or custom project
Search for an official set by number or name, open its inventory, and track the parts you have found and the quantities still missing. When you choose to use collection recovery, BrickzBack checks the selected set against loose pieces you have marked available. You decide what to confirm or commit.
Projects use a similar checklist for custom builds. Import a compatible Studio model or parts list, then review the required pieces against available inventory. This helps you plan a build without counting the same loose part toward two plans.
BrickzBack helps you check a selected set or project; it does not promise to automatically find every possible build for every collection.
Follow value and prepare your next step
Review BrickzBack’s value guidance for supported collection items, keep a manual value when that suits you, and follow value history over time. Estimates can differ from actual selling prices and are not offers or guarantees.
When you are ready to sell, Trader turns details you have confirmed into an editable draft and helps track sale outcomes and profit or loss. You choose where to publish it and handle the transaction; BrickzBack does not publish listings or manage payment and shipping.
Frequently asked questions
What can I track in BrickzBack?
BrickzBack helps organise LEGO sets, minifigures, loose parts and wishlist items. Builds and projects, value history and Trader drafts connect to your collection while staying in their own workspaces.
How do I use pieces I already own in a build?
Open a selected set or custom project and check its parts list against loose pieces marked available. BrickzBack shows what remains, while you decide whether to confirm or commit each piece.
Can BrickzBack show me builds that fit my collection?
BrickzBack helps you find official sets and check a selected set inventory against pieces you have marked available. You can also check a custom project list against your collection. It does not promise every possible build will be fully matched automatically.
Are collection values guaranteed sale prices?
No. BrickzBack provides value guidance for supported items and lets you keep manual values. Market conditions and item condition affect actual sale prices; estimates are not offers or guarantees.
Does Trader sell or list items automatically?
No. Trader creates an editable draft from details you confirm. You choose where to publish it and handle communication, payment and shipping.
Can I import a custom project?
Yes. You can import a compatible Studio model or parts list into a custom project checklist, then review its parts and check them against pieces marked available.
