About BrickCheck

BrickCheck (one word, found at brickcheck.app) is the LEGO® collection tracker that treats your sets like a stock portfolio. Scan a box barcode, and BrickCheck identifies the set, pulls its live market value, and adds it to your collection — then keeps every price up to date automatically.

We aggregate real marketplace data across sealed and used conditions for more than 25,000 sets, turn it into clean price histories and portfolio analytics (total value, gains, CAGR, theme diversification), and alert you the moment a set you care about moves.

BrickCheck is an independent product and is not affiliated with the LEGO Group, nor with other similarly-named tools such as retail stock checkers. If you found us while searching for a way to know what your LEGO collection is worth — you're in the right place.
