Collectors who stopped guessing

4.8 / 5 from early users tracking their sets

★★★★★
I had 40 sets in the loft with no idea what they were worth. In ten minutes I saw my collection was up over $3,000. Sold two retired sets that week.

The retirement alerts are the killer feature. I buy sets before they retire and the value jumps. This paid for itself the first month.

Finally real BrickLink prices instead of made-up estimates. Clean, fast, and the ROI view makes it obvious what to hold and what to flip.

I flip Star Wars sets on the side. The eBay profit calculator alone saves me an hour a week and I finally know my real margins.

My wife thought my LEGO habit was a waste of money. Then I showed her the dashboard: up 34% in two years. Now she picks sets too.

The price-per-piece index is genius for spotting a deal at retail before everyone else does. Bagged two sets that already climbed.

I run a small shop and the multi-copy tracking plus PDF report is exactly what I needed for inventory and insurance. Huge time saver.

Got an email the day the Bonsai retired, sold my spare for double what I paid. That one alert was worth a year of the subscription.

Simple, fast, no fluff. I check my portfolio value every Sunday with coffee. It's become my little market ritual.

Tried three other trackers. This is the only one with real sold prices and it works right in the browser, no clunky app. Switched for good.

FAQ
Good questions
Where do the prices come from?

Live listings from the BrickLink marketplace (the world's biggest LEGO secondary market), plus official retail prices and retirement dates. Updated daily.

Is it accurate?

We show real market prices (new and used, min, average and max), not a black-box estimate. You always see the range.

How do "sell now" alerts work?

When a set you own retires or hits a new price high, we ping you. That's usually the best window to sell.

Can I import my whole collection?

Yes. Bulk CSV import is available on the Investor plan, with multi-copy tracking for resellers.

Can I cancel anytime?

Anytime, in one click. No lock-in.
