DONNA | Tech Stack & Analysis

What we found

There are no SPF or DMARC records, so anyone can send email that claims to come from this domain.
It sends three of the six security headers we check; Content-Security-Policy is among those missing.
The page is missing a canonical URL.
Built with Lovable and React, the site is served through Cloudflare, with a domain registered 10 months before launch.
One more gap is listed further down the page.

Email

Record	Status	What it does
SPF	Not published	Lists the servers allowed to send email for the domain.
DMARC	Not published	Tells receivers what to do with email that fails SPF or DKIM.
DKIM	Not found at common selectors	Signs outgoing email. We check common selectors only, so a provider may use another.
MTA-STS	Not deployed	Stops email to the domain being downgraded to plain text in transit.
TLS-RPT	Not configured	Sends the owner reports of failed encrypted deliveries.

Without SPF and DMARC, anyone can send email that claims to come from this domain. Those two are the records to add first.

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.
