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 14 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.

Mercury ships with the basics, with a complete set of security headers, a thorough launch checklist, and fast page loads. Visible gaps: incomplete legal pages, no robots.txt or sitemap, and incomplete email security.

Launched on Hacker News on April 13, 2026. The site is hosted on Railway, with a domain registered 4 months before launch. We've detected 14 technologies on this site, covering hosting, analytics, auth, and baas. The stack includes Auth0, Next.js, and React.

It's one of only 37 launches we've crawled running Auth0 and more locked down than the typical Hacker News launch.

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.
