What Brick HQ is
The command center for your LEGO® collection — whether you build for joy or invest for the future.
Everything you'd otherwise keep in a spreadsheet and six browser tabs, in one app: what you own, what you're watching, what it's worth, and what it costs today. It runs on a catalog of every set, every minifigure and every part, so the answer is there whether you're standing in a store or sorting a bin of loose bricks at home.
Track retailer deals
Brick HQ checks five retailers — Target, Walmart, Amazon, Barnes & Noble and Kohl's — and shows what each is charging right now. Every discount is measured against the set's real MSRP, not a store's own "was" price, so a 30% off badge means 30% off LEGO’s MSRP. Set a price or a percentage on anything you're watching and you'll get a notification when it hits.
Shop and track eBay listings
Live eBay listings with prices, photos, and seller ratings, so you can shop active and retired sets without leaving the app. Alongside them sit BrickLink sold averages, which show what people actually paid rather than what someone is asking. Set a price and condition on any set and you’ll get a notification when a listing appears below it.
Track your collection two ways
Two ways to look at the same sets. Collector mode is about the building: what's still sealed, what's built, what's part-way through, which sets are missing pieces, and how far into a theme you are. Investor mode is about the money: what you paid, what each set is worth now from retail and BrickLink values, your unrealized gains, and the ROI across the whole portfolio. Switch between them whenever you like — it's one collection either way, just two questions you might be asking of it.
See everything about a set
Open any set and you get the whole picture. Every minifigure it includes, its piece count, whether it's retiring, how the BrickSet community rates it — and a link to the building instructions. Scroll on and there's what each retailer is charging, a price history chart so you can tell whether today's discount is actually unusual, and its BrickLink value. If you're deciding whether to buy now or wait, the answer is usually on this screen.
Build with the parts you have
Mark a set as parted out and its bricks join your loose-parts pool. Can Build then tells you which other sets those parts could complete — matching either exactly on color, or allowing any color where a brick in the wrong shade still counts toward the build.
Going the other way, pick a set you want to build and get its full parts checklist, drawn from 1.17 million parts records. It tracks how many of each part you have sourced so far, and every part links straight out to a BrickLink search for that exact piece, so you can go and find the ones you are missing. Where the catalog has them, there is a link to the building instructions too.
Track every minifigure
17,907 minifigures, each one linked to every set it appears in — so you can work out which set to buy for the figure you're after, or what a loose figure came from. Track them alongside your sets: in Investor mode each owned figure carries its BrickLink sold average, new and used, and rolls into your portfolio value the same way a set does.
