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 29 August 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.

SlumberWave 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 August 29, 2026. The site is served through Cloudflare, with a domain registered in 2023. The crawl picked up 11 technologies on this site, covering analytics, security, CDN, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 5,611 other launches and tighter on security headers than most Product Hunt launches.
