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 12 May 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.

LeadSave ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing Referrer-Policy and Permissions-Policy.

Launched on Product Hunt on May 12, 2026. The site is hosted on Google Cloud. We've detected 7 technologies on this site, covering hosting, auth, web fonts, and protocol. The stack includes Google Sign-In, Google Cloud, and Google Developer Site.

It's a rare Google Developer Site sighting, just 3 in our data and tighter on security headers than most Product Hunt launches.
