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 11 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.
Blue eSIM ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: no Permissions-Policy, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on April 10, 2026. The site is hosted on Vercel, with a domain registered in 2024. Our crawler found 21 technologies on this site, covering advertising, business email, social embeds, and analytics. The stack includes Auth.js, Next.js, and React.
It's also running the same core stack as 14,977 other launches and tighter on security headers than most Product Hunt 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.
