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 23 June 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.

CentralTab — New Tab Browser Extension is early-stage. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 23, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 8 months before launch. We've detected 13 technologies on this site, covering javascript library, analytics, backend framework, and CSS frameworks. The stack includes Bootstrap, ASP.NET, and Dyna-NS.

It's on one of the most common stacks we track, shared by 613 launches.
