What we found
- Analytics set tracking cookies before any opt-in, and we found no consent manager.
- It sends five of the six security headers we check; the missing one is Content-Security-Policy.
- DMARC only monitors (p=none), so email spoofing this domain is still delivered.
- Built with Next.js and React, the site is hosted on Vercel, with a domain registered in 2025.

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 10 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.
