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 21 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.
CalcHub ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and incomplete email security.
Launched on Product Hunt on April 21, 2026. The site is served through Cloudflare. Our crawler found 16 technologies on this site, covering advertising, security, AI builders, and CDN. The stack includes CookieYes, Tailwind CSS, and Cloudflare.
It's also running the same core stack as 7,712 other launches.

Readiness Breakdown How?
Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| AI writing signals | +3 |
| AI iconography signals | +3 |
| Recognised AI builder signature | +100 |
| Unfilled template placeholders | +10 |
| Default scaffold favicon | +10 |
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.
