Own this Launch?

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 29 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.

haz.tools is largely in shape, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on April 29, 2026. The site is hosted on IONOS and served through Cloudflare, with a domain registered 3 days before launch. The crawl picked up 8 technologies on this site, covering analytics, CDN, DNS providers, and business email. The stack includes Cloudflare, Cloudflare DNS, and Google Analytics.

For context, it's on one of the most common stacks we track, shared by 180 launches.
