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 June 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.
FocusStack is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing several security headers and tracking cookies set before any opt-in.
Launched on Product Hunt on June 28, 2026. The site is hosted on AWS S3 and served through AWS CloudFront, with a domain registered 1 week before launch. The crawl picked up 10 technologies on this site, covering analytics, CDN, cloud, and developer tools. The stack includes Amazon SES, Amazon Web Services, and AWS CloudFront.
For context, it's running the same core stack as 512 other launches.
