Screenshot of Nebenkosten: Klartext

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 30 June 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.

Nebenkosten: Klartext is partway there, with a thorough launch checklist, fast page loads, and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 30, 2026. The site is hosted on AWS S3 and served through AWS CloudFront. The crawl picked up 12 technologies on this site, covering ui library, analytics, CDN, and cloud. The stack includes Tailwind CSS, Vue.js, and Amazon Web Services.

For context, it's on a stack we've seen on only 19 launches.
