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 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.

SIMZY scores highly overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers.

Launched on Product Hunt on August 28, 2026. The site is hosted on AWS S3 and served through AWS CloudFront, with a domain registered in 2010. The crawl picked up 35 technologies on this site, covering advertising, social embeds, analytics, and CDN. The stack includes Amazon, Auth0, and Cookiebot.

For context, it's one of only 34 launches we've crawled running Auth0.

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.
