Seerist Space | Tech Stack & Analysis

What we found

Analytics set tracking cookies before any opt-in, and we found no consent manager.
It sends one of the six security headers we check; Content-Security-Policy is among those missing.
It publishes DMARC but no SPF record, so receivers cannot tell which servers may send its email.
Built with Next.js and React, the site is hosted on Vercel and served through Cloudflare.
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 p=none	Monitoring only (p=none) (from seerist.xyz)	Tells receivers what to do with email that fails SPF or DKIM.
DKIM	Found (from seerist.xyz)	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, receivers cannot tell which servers may send email for this domain.

Notes

Looks AI-built: some AI signals. How much the site looks AI-generated. It is a pattern match shown for interest, not a verdict.

Which signals fired

Signal	Points

AI palette signals	+5
AI writing signals	+5
AI iconography signals	+3
AI stack signals	+10

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 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.
