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 1 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.

Jigsudo is partway there, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on May 1, 2026. The site is hosted on GitHub Pages and served through Cloudflare, with a domain registered 3 months before launch. The crawl picked up 13 technologies on this site, covering CDN, baas, consent tooling, and DNS providers. The stack includes Google, Cloudflare, and Cloudflare DNS.

For context, it's running the same core stack as 2,675 other launches.
