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 1 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.
CalculeOnline is largely in shape, with a thorough launch checklist, fast page loads, and clean crawl signals. What needs work: no Content-Security-Policy, incomplete legal pages, and tracking cookies set before any opt-in.
Launched on Hacker News on May 1, 2026. The site is hosted on Vercel, with a domain registered 3 weeks before launch. The crawl picked up 13 technologies on this site, covering advertising, analytics, CSS frameworks, and DNS providers. The stack includes Astro, Tailwind CSS, and Banco Central do Brasil API.
For context, it's running the same core stack as 217 other launches and tighter on security headers than most Hacker News launches.

| AI onboarding signals | +5 |
| AI writing signals | +5 |
| 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.
