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 19 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.
React Email 6.0 by Resend ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist.
Launched on Product Hunt on April 18, 2026. The site is hosted on Vercel and served through Bunny CDN, with a domain registered in 2002. Our crawler found 39 technologies on this site, covering analytics, developer tools, web fonts, and seo. The stack includes Google Sign-In, Next.js, and React.
It's also on a stack we've seen on only 8 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.
