From a parts list to a finished build
Add a MOC parts list
Upload a Rebrickable CSV, a BrickLink XML inventory, or a Studio .io file. Your MOC opens as a tab and tracks like any official set.
Find the pieces
Filter by category and color, sort the list however you like to dig, and check off each piece you already own as it turns up in your bins.
Order what's missing
When the bins run dry, export only the pieces you still need as a BrickLink, Brick Owl, or Rebrickable list and order the rest.
Free for 14 days. Cancel any time.
What is free, and what needs Plus

- Which files can I import?
- A Rebrickable parts CSV, a BrickLink XML inventory, or a Studio
.iofile. Raw LDraw files and importing straight from a URL are not supported yet, so download the parts list first. - Can it tell me what I can build from my parts?
- No - that is a different job. Brick Party starts once you have chosen a MOC and have its parts list. It helps you pick those parts out of your own collection, and order whatever you are missing.
- Does this work for alternate builds and B-models?
- Yes, as long as you have a parts list for it. An alternate build made from a set you already own is the case this handles best, since most of the parts should match.
- Do I need Plus?
- MOC import is a Plus feature. Everything else - set inventories, part tracking, photo identification, and exports - works on a free account. Plus is $8/month or $80/year, and new accounts can try it free for 14 days. Compare plans.
- What happens when the trial ends?
- You keep your free account and everything on the free plan - set inventories, part tracking, and exports are unaffected. Imported MOCs are hidden from your collection while you are on the free plan, but nothing is deleted: subscribe again and they are all still there. Cancel any time during the 14 days and you are not charged.
