Own this Launch?

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 12 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.

Fastsleep.app (Dark UI) is missing several launch fundamentals. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on April 12, 2026. The domain was registered 6 weeks before launch. Our crawler found 5 technologies on this site, covering business email, developer tools, DNS providers, and servers. The stack includes Jellyfish Cloud Email, LiteSpeed Web Server, and Namecheap DNS.
