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 29 June 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.
SheetGuard is largely in shape, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: no robots.txt or sitemap and incomplete email security.
Launched on Product Hunt on June 29, 2026. The site is served through Cloudflare. The crawl picked up 18 technologies on this site, covering security, analytics, auth, and captcha. The stack includes Clerk, Next.js, and React.
For context, it's on one of the most common stacks we track, shared by 5,882 launches and more locked down than the typical Product Hunt launch.

Readiness Breakdown How?
Performance How?
Indicative grade from a single automated render, not a substitute for Lighthouse or field data, and not part of the StackScope score.
Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| AI copy signals | +5 |
| AI palette signals | +5 |
| AI layout 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.
