Rebrickable

LEGO set, part, color, and MOC catalog data in WhichBrick is provided by Rebrickable, used as the source of that data under the Rebrickable API terms. This includes the set and part catalog the app ships with and the MOC suggestions ("what can we build from the sets we own?") that make WhichBrick work.

MOC designs shown in the app belong to their individual designers; the app links each MOC back to its page on Rebrickable, where the designer is credited.

Brickset

Set photography, additional set images, and building-instruction links are provided by the Brickset API, used with acknowledgement of Brickset as the source of that data. Brickset has documented the LEGO catalog since 1997 and is the reference the app's set galleries lean on.

Typefaces

The app and this site use Lexend, licensed under the SIL Open Font License, chosen because its single-storey letterforms match the shapes emerging readers are taught first.
