Quartet — Find aircraft in Sentinel-2 satellite imagery

This site was found by StackScope Discovery, our own first-party launch detection. The tech stack below comes from that discovery scan; the full analysis (screenshots, scores, page checks) is added when the site is picked up by a launch platform.

Quartet spots aircraft in free Sentinel-2 satellite imagery from the four offset colored dots a moving plane leaves across the color bands, then identifies each one against ADS-B flight data.

Own this Launch?

StackScope records what new websites are built with, the week they launch. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We crawled this one to detect its tech stack. This page is what we saw on 29 July 2026; the live site may have changed since.

Every technology below links to its own page: which other new sites launched with it. Vendors and agencies watch those pages with Stackdar and hear about new adopters the week they ship, from £15 a month.
