MOC Source tekijä moc-source

MOC Source overlays live LEGO Pick a Brick (PAB) and Bricks and Pieces (BAP) prices directly onto BrickLink.com — on wanted lists, store carts, store listings, and catalog pages — so you can see at a glance whether a part is cheaper from LEGO direct or from the BrickLink store you're browsing.

Click the toolbar icon to open the built-in list manager: import your BrickLink wanted lists and store carts, track Want/Have quantities, and compare LEGO-direct pricing part by part. The Projects workspace lets you split a wanted-list pool across multiple LEGO Pick-A-Brick carts and BrickLink store carts, auto-allocating each part to its cheapest source and tracking savings including shipping.

Price badges work on BrickLink's public pages with no account needed. Importing your own wanted lists/carts requires a free BrickLink.com account (data stays local to your browser). LEGO cart transfer requires a LEGO.com login.

Free and open source (AGPL-3.0). Built by an AFOL, for AFOLs — not affiliated with the LEGO Group or BrickLink.
