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 28 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.
Quldra ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing Content-Security-Policy and Strict-Transport-Security and incomplete email security.
Launched on Product Hunt on April 28, 2026. The site is hosted on DigitalOcean in the United States, with a domain registered 3 months before launch. We've detected 6 technologies on this site, covering DNS providers, business email, web fonts, and os. The stack includes Google Fonts, Google reCAPTCHA, and nginx.
It's tighter on security headers than most Product Hunt launches.

Readiness Breakdown How?
Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| AI palette signals | +5 |
| AI writing signals | +5 |
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.
