Screenshot of Seleen

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 6 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.

Seleen has the basics covered well, with complete legal pages and a thorough launch checklist. Visible gaps: missing Permissions-Policy and Content-Security-Policy, no robots.txt, and incomplete email security.

Launched on Product Hunt on May 6, 2026. The site is hosted on Vercel, with a domain registered 2 weeks before launch. Our crawler found 7 technologies on this site, covering DNS providers, email forwarding, frameworks, and hosting. The stack includes Next.js, React, and Google Search Console.

It's also on one of the most common stacks we track, shared by 3,469 launches and more locked down than the typical Product Hunt launch.
