What we found
- Analytics set tracking cookies before any opt-in, and we found no consent manager.
- There are no SPF or DMARC records, so anyone can send email that claims to come from this domain.
- It sends one of the six security headers we check; Content-Security-Policy is among those missing.
- Built with Astro and Svelte, the site is hosted on Vercel.
- One more gap is listed further down the page.

Notes
- Looks AI-built: no AI signals. How much the site looks AI-generated. It is a pattern match shown for interest, not a verdict.
- Performance comes from one render on 8 November 2026 and will vary between visits.
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.
