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.
Extralt ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.
Launched on PeerPush on May 1, 2026. The site is served through Cloudflare, with a domain registered in 2025. The crawl picked up 16 technologies on this site, covering analytics, security, auth, and CDN. The stack includes Clerk, Tailwind CSS, and Cloudflare.
For context, it's running the same core stack as 7,750 other launches and tighter on security headers than most PeerPush launches.

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.
