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 15 May 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.

SKILLCert by AI scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing Permissions-Policy and Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on May 15, 2026. The site is hosted on AWS S3 and served through AWS CloudFront, with a domain registered 10 months before launch. The crawl picked up 12 technologies on this site, covering advertising, analytics, CDN, and cloud. The stack includes Astro, Amazon SES, and Amazon Web Services.

For context, it's one of just 25 launches we've crawled on this exact stack and more locked down than the typical Product Hunt launch.
