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 27 July 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.

Port Zero — stable domains for your local dev ports scores highly overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: no Content-Security-Policy.

The site is hosted on DigitalOcean in the United States, with a domain registered 2 weeks before launch. Our crawler found 10 technologies on this site, covering DNS providers, analytics, business email, and transactional email. The stack includes Astro, Caddy, and Cloudflare DNS.
