Screenshot of StudentOS

What we found

  1. It sends none of the six security headers we check.
  2. It has terms of service, but we found no privacy policy.
  3. DMARC only monitors (p=none), so email spoofing this domain is still delivered.
  4. Built with Express and React, the site is hosted on Google Cloud, with a domain registered in 2023.

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.

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 If a technology shown here is wrong or out of date, email [email protected] and we'll review it.
