What we found
- It sends none of the six security headers we check.
- DMARC only monitors (p=none), so email spoofing this domain is still delivered.
- Built with Astro, the site is served through Cloudflare, with a domain registered 6 months before launch.
- It welcomes AI crawlers and publishes an llms.txt.

How we know
FirstSited records what new websites are built with, usually within a day of going live. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We checked this one in full: its tech stack, DNS, security headers and page basics. This page is what we saw on 8 November 2026; the live site may have changed since.
Every technology below links to its own page: which other new sites launched with it. Watch any of them and get every new site that uses it as it goes live, from £15 a month.
