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 6 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.
40-15 App has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.
Launched on Product Hunt on May 6, 2026. The site is hosted on Soluciones Corporativas IP SCIP in Spain, with a domain registered 9 weeks before launch. Our crawler found 8 technologies on this site, covering baas, DNS providers, business email, and transactional email. The stack includes Apache, DonDominio, and DonDominio Mail.

| AI writing signals | +5 |
| AI code-structure signals | +10 |
| Recognised AI builder signature | +30 |
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.
