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 21 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.

BounceZero 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 April 21, 2026. The site is hosted on OVH in France. We've detected 17 technologies on this site, covering advertising, payments, social embeds, and analytics. The stack includes CookieYes, Tailwind CSS, and Amazon SES.

It's running the same core stack as 7,750 other launches and tighter on security headers than most Product Hunt launches.
