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 28 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.

Sensyk is partway there, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers, no robots.txt or sitemap, and tracking cookies set before any opt-in.

Launched on Product Hunt on May 28, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 5 months before launch. The crawl picked up 14 technologies on this site, covering security, seo, analytics, and auth. The stack includes Clerk, Next.js, and React.

For context, it's on one of the most common stacks we track, shared by 14,964 launches.
