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 17 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.

Attendance Calculator Online - Check 75% has the basics covered well, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on June 17, 2026. The site is hosted on Google LLC in the United States, with a domain registered 3 weeks before launch. Our crawler found 9 technologies on this site, covering advertising, analytics, CMS, and DNS providers. The stack includes Blogger, cdnjs, and Facebook Pixel.

It's also one of 56 launches on this exact stack.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
