Screenshot of Puzzle

What we found

  1. It sends two of the six security headers we check; Content-Security-Policy is among those missing.
  2. DMARC only monitors (p=none), so email spoofing this domain is still delivered.
  3. The page is missing a canonical URL.
  4. Built with Webflow, the site is served through Cloudflare.

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 If a technology shown here is wrong or out of date, email [email protected] and we'll review it.
