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 31 August 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.

Reverse Tax Calculator is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers, tracking cookies set before any opt-in, and no email security records.

Launched on Product Hunt on August 31, 2026. The site is served through Cloudflare, with a domain registered 6 weeks before launch. The crawl picked up 8 technologies on this site, covering wordpress plugin, analytics, CDN, and CMS. The stack includes WordPress, Cloudflare, and Cloudflare DNS.

For context, it's running the same core stack as 1,570 other launches.
