Rebrickable will look at all the parts in all the sets you own, as well as all the loose parts you may have added. It then calculates how much of each set or MOC you have, based on those parts. If specified, it can ignore colors in these calculations or use some fuzzy logic to equate close matching colors such as yellow and orange.
Some of the original inventory listings and part details for the official LEGO sets came from BrickLink and Peeron. However, we have modified a lot of them to be more suitable for the "rebrickability" features of this site. Also, due to TOS changes at Bricklink, we no longer rely on any data from them and use the freely available inventory data from LEGO.com and our own instruction manuals instead. See this forum post for more details. Any user can submit their own inventories for sets we have not yet added. The MOC inventories are submitted by the individual MOC designers, or were manually entered from photos of the parts.
New sets are added as they become known to us, or users submit an inventory for a new set. Since it takes time for newly released sets to be fully cataloged, there is a delay before it is added to the Rebrickable database. In some cases, certain sets have been purposefully excluded from the database (Duplo!). Of course there are also times when a set has just been overlooked. If you think a set should be there but isn't please contact us or submit it yourself via the Set Designer.
There are many ways you can help us out:
Rebrickable's parts are based (mostly) on the LDraw numbering scheme. For any features that rely on importing or exporting to external websites or applications, automatic part number conversions are done to prevent any problems.
MOC simply stands for "My Own Creation" and is a term used to cover all the fan-based LEGO creations other than the officially released sets. Rebrickable stores hundreds of user-submitted MOCs all with building instructions.
We accept MOC submissions from anyone via the MOC Designer page. To be approved, your MOC must meet some basic requirements:
You do not have to have your own website, you can use Bricksafe for free LEGO file storage.
We accept MOC submissions from anyone via the MOC Designer page. You can add parts to your MOC manually via the Part Picker, or if you have a MPD or LDR file you can import it directly and let Rebrickable figure out which parts are in it.
