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 July 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.

JSON Toolbox by mackan.eu ships with the launch fundamentals in place, with a complete set of security headers, a thorough launch checklist, and well-configured email security. What needs work: incomplete legal pages.

Launched on Product Hunt on July 11, 2026. The site is served through Cloudflare. We've detected 20 technologies on this site, covering package cdn, data api, javascript library, and maps. The stack includes AnonAddy, cdnjs, and Cloudflare.

It's tighter on security headers than most Product Hunt launches.
