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 for its tech stack and scored it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 29 August 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.

ERD Online covers some of the launch checklist, with a thorough launch checklist, fast page loads, and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on August 29, 2026. The site is served through Bunny CDN, with a domain registered in 2023. Our crawler found 6 technologies on this site, covering CDN, analytics, DNS providers, and web fonts. The stack includes Bunny CDN, Bunny Fonts, and Cloudflare.
