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 21 June 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.

Fupio scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: incomplete email security.

Launched on Hacker News on June 21, 2026. The site is served through Cloudflare, with a domain registered in 2015. We've detected 11 technologies on this site, covering baas, CDN, directory, and DNS providers. The stack includes Astro, Cloudflare, and Cloudflare DNS.

It's on one of the most common stacks we track, shared by 573 launches and more locked down than the typical Hacker News launch.
