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 22 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.

Duo has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers.

Launched on Product Hunt on May 22, 2026. The site is hosted on Namecheap in the United States, with a domain registered 5 months before launch. Our crawler found 5 technologies on this site, covering servers, web fonts, security, and seo. The stack includes Google Fonts, Google Search Console, and HSTS.
