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 29 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.
Add Signature is largely in shape, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.
Launched on Product Hunt on April 29, 2026. The site is hosted on Onecom in Denmark, with a domain registered 3 months before launch. The crawl picked up 6 technologies on this site, covering servers, DNS providers, business email, and package cdn. The stack includes Apache, cdnjs, and Google Search Console.

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.
