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 13 April 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.

Duck – ASO Tool is early-stage. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on April 2, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 4 days before launch. We've detected 11 technologies on this site, covering analytics, security, auth, and CDN. The stack includes Clerk, Tailwind CSS, and Cloudflare.
