What we found

It publishes SPF but no DMARC record, so receivers decide for themselves what to do with email that fails.
It has no robots.txt or sitemap, the two files that help search engines find its pages.
The page is missing Open Graph sharing tags, a canonical URL, and Twitter card tags.
Built with Next.js and React, the site is hosted on Vercel.

Email

Record	Status	What it does
SPF ~all	Soft-fail (~all), common and accepted (from confluencebuild.xyz)	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 DMARC, receivers fall back to their own rules for email that fails SPF.

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 10 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 10 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.
