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 7 July 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.
Fenzo AI is largely in shape, with a thorough launch checklist, well-configured email security, and clean crawl signals. What needs work: missing several security headers and incomplete legal pages.
Launched on Product Hunt on July 7, 2026. The site is hosted on Google Cloud and served through Cloudflare, with a domain registered 10 months before launch. The crawl picked up 20 technologies on this site, covering analytics, advertising, CDN, and chat widgets. The stack includes Google, Next.js, and React.
For context, it's running the same core stack as 139 other launches.

Vibe Score Breakdown How?
| Signal | Points |
|---|---|

| 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.
