Rebrickable

Rebrickable is an independent LEGO fan database. Not a shop, not a marketplace — a free information platform. Founded in 2012 by an Australian fan, it's still community-run, now with over 300,000 alternative building instructions (MOCs) and extensive data on every official LEGO set ever released.

What they do

• Set database: all official LEGO sets with parts lists, minifigures, themes and years
• Parts database: almost every LEGO part with IDs, colours and which sets contain them
• MOCs: fan-designed building instructions, some free, others for a small fee (€3-€10)
• Alt builds: MOCs made from the bricks of a specific official set — no extra parts needed
• "Build Possible" tool: enter your own collection and see which sets/MOCs you can build with your current bricks

Where Lakea uses Rebrickable

Via their API we fetch:

• The alt-build count per set (the "???? alt builds" button in accessories)
• Links to individual MOC pages on rebrickable.com
• Set metadata as a cross-check against our other sources (LEGO PDF, Brickset)

We earn no commission if you buy via Rebrickable — that's not the point. It's simply a better source for MOCs than any other platform.
