Mark sets you're hunting along with a target price. Steinwert shows you the daily distance to market value (median of active eBay-DE listings). Email-on-hit lands once the mail path is wired.
EOL radar · Q4 2026
Sets typically gain 25–40 % on the secondary market once LEGO retires them. That's the reason this feature exists. We're building it openly: sources, methodology and hit rate will live on a public status page.

ExampleWhat a set looks like inside the app.

FAQSix questions, answered honestly.
01Where does the price data come from?
Two sources, both refreshed daily. Brickset returns MSRP per region (DE, UK, US, CA); Steinwert takes the lowest EUR value after conversion. eBay-DE delivers the market value as the median of active Buy-It-Now listings, filtered to complete sets (listings below 30 % of MSRP are excluded, which strips parts, minifigs, and instructions-only listings). Sample size is shown openly. BrickLink stays closed: their API requires a registered-seller status we don't have.
02How does the EOL radar actually work?
Right now it doesn't: the feature is planned for Q4 2026. The plan: combine list-price moves across DACH retailers, Brickset's own status fields (released/exitDate) and LEGO press releases. Once the first version ships, sources and hit rate will live on a public status page, no black box.
03Is Steinwert affiliated with the LEGO Group?
No. Steinwert is an independent single-person project with no connection to the LEGO Group or its subsidiaries. “LEGO”, “BrickLink”, “Brickset” and similar marks remain property of their respective owners and are used here only nominatively.
04Which sets are in the index?
Over 10,000 sets from year 2000 onward, pulled from the public Rebrickable dataset. Polybags, promo sets and minifigure series are deliberately excluded for now; they'll be added once collectors actually ask for them. A set missing? An email is enough.
05Where is my data stored?
Inside the EU/EEA. Web app on Vercel, EU region Frankfurt. Database on Supabase / AWS Ireland (eu-west-1). Both GDPR-compliant, no ads, no third-party trackers. Wiping your collection today happens by email; a self-service delete is in the works.
06What about Lifetime after the beta?
Lifetime is not yet activated during the beta: we don't take money for unfinished features. Once Pro goes live, Lifetime opens too: € 149 one-time, all Pro features forever, capped at 500 seats. Free users hear about it first by email.
