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 3 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.

Fasten is partway there, with fast page loads. Visible gaps: missing several security headers, placeholder text in the legal pages, and no sitemap.

Launched on Product Hunt on June 3, 2026. The site is served through Cloudflare, with a domain registered 4 weeks before launch. The crawl picked up 5 technologies on this site, covering CDN, DNS providers, business email, and protocol. The stack includes Apple Business Connect, Apple iCloud Mail, and Cloudflare.
