Screenshot of DiffLens - Local-first structured text diff

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 for its tech stack and scored it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 28 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.

DiffLens - Local-first structured text diff is partway there, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

The site is hosted on Scloud Pte Ltd in Singapore. The crawl picked up 9 technologies on this site, covering analytics, developer tools, DNS providers, and os. The stack includes Baidu Tongji, Google Analytics, and Google Search Console.
