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 23 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.
Speechmatics On-Device is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers.
Launched on Product Hunt on April 23, 2026. The site is hosted on Vercel, with a domain registered in 2006. The crawl picked up 29 technologies on this site, covering advertising, ai api, analytics, and business email. The stack includes Contentful, Cookiebot, and Next.js.
For context, it's one of just 8 launches we've crawled on this exact stack.
