Added July 22, 2026 · Last analysed August 22, 2026 · via StackScope Discovery · also on Product Hunt

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 22 August 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.

Free Online Financial Calculators | Percentio ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: tracking cookies set before any opt-in and incomplete email security.

The site is hosted on Hostinger. The crawl picked up 16 technologies on this site, covering advertising, hosting, ui library, and AI builders. The stack includes Tailwind CSS, Cloudflare DNS, and Google Ads.

For context, it's running the same core stack as 114 other launches and tighter on security headers than most StackScope Discovery launches.

Recognised AI builder signature +100

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.
