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 11 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.

Product PlayGround ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing several security headers.

Launched on Product Hunt on April 9, 2026. The site is served through Cloudflare. Our crawler found 16 technologies on this site, covering analytics, security, advertising, and AI builders. The stack includes Tailwind CSS, Amplitude, and Cloudflare.

It's also running the same core stack as 7,750 other launches.
