What you own. What it's worth. What's next.
Log every LEGO® set and minifig you own and see what each one actually sells for: real completed sales, never asking prices, with the number of sales behind every figure.
What it does.
Your shelf, catalogued
Scan a barcode, snap a photo, or search by name. Stud Stacks pulls the catalogue entry, release year and price history for each set.
Real sold prices
Values come from completed BrickLink sales, not listings. Each figure is the median of recent sales, and you see how many sales it rests on and when the last one was.
Minifigures, a tray at a time
Photograph a tray of figures and each one is identified and valued individually. Over 15,000 minifigures in the catalogue.
Retirement, dated
See which sets have just left retail, with the date, and where each one sits against its original price. Retirement is where a set's value story starts.
Export the audit trail
CSV for insurance, your accountant, or your own records. BrickLink XML for BrickStore, Bricqer and BrickTrac. Every line, every date, every price.
Theme drilldown
See which themes are pulling their weight: Star Wars vs. Modular vs. Icons, sliced by what you paid and what it is worth now.
Free during early access.
Stud Stacks is free while it is in early access. A paid tier will be announced before launch, and it will not put your scans or your collection's value behind a paywall.
Common questions.
Is Stud Stacks affiliated with The LEGO Group?
No. Stud Stacks is an independent product for adult LEGO® collectors. Not affiliated with, endorsed, or sponsored by The LEGO Group.
Where does the price data come from?
Completed sales on BrickLink, the largest LEGO® marketplace. Never asking prices. Each value is the median of recent sales, and the app shows how many sales it is based on and the date of the most recent one, so a thin or stale figure is visible as such. Prices are requested in pounds directly.
How accurate is it?
As accurate as the market is. Individual sales of the same item vary, often by 25% or more either side of the median, so a valuation is a fair estimate of what it would sell for, not a guarantee. Where there are too few recent sales to say, the app tells you rather than inventing a number.
Do I need to pay to use it?
Not during early access. A paid tier will be announced before launch. Scanning and valuation will remain free.
What if I sell an item?
Mark it as sold with the sale price and date. Stud Stacks keeps it in your history for realised-gain tracking without cluttering your active shelf.
Which platforms are supported?
