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 2 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.

Churnkey SDK scores highly overall, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 2, 2026. The site is served through Cloudflare. We've detected 6 technologies on this site, covering analytics, CDN, CSS frameworks, and frameworks. The stack includes React, Tailwind CSS, and Cloudflare.

It's on one of the most common stacks we track, shared by 305 launches.
