What we found
- We found no privacy policy or terms of service.
- It sends one of the six security headers we check; Content-Security-Policy is among those missing.
- It publishes SPF but no DMARC record, so receivers decide for themselves what to do with email that fails.
- Built with Capacitor and React, the site is hosted on Vercel, with a domain registered 3 months before launch.
- Two more gaps are listed further down the page.

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 7 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.
