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 26 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.

PyPie is missing several launch fundamentals. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on May 26, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered 8 months before launch. Our crawler found 4 technologies on this site, covering CDN, DNS providers, business email, and hosting. The stack includes Fastly, Fastmail, and GitHub Pages.

It's also on one of the most common stacks we track, shared by 2,676 launches.
