What we found

Analytics set tracking cookies before any opt-in, and we found no consent manager.
DMARC only monitors (p=none), so email spoofing this domain is still delivered.
Built with Next.js and React, the site is served through Cloudflare, with a domain registered 8 months before launch.
It welcomes AI crawlers and publishes an llms.txt.

Built with: 24 technologies

Analytics set tracking cookies on our visit and no consent manager was detected. UK and EU GDPR require opt-in before tracking runs, and more than 20 US states require honouring opt-out requests.
Performance comes from one render on 13 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 13 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.

Spot a mistake? If a technology shown here is wrong or out of date, email [email protected] and we'll review it.
