HearHear | Tech Stack & Analysis

What we found

Analytics set tracking cookies before any opt-in, and we found no consent manager.
It sends five of the six security headers we check; the missing one is Content-Security-Policy.
Built with React and Supabase, the site is hosted on Vercel and served through Cloudflare, with a domain registered 3 months before launch.
It blocks AI crawlers in its robots.txt but also publishes an llms.txt for them.

Notes

Looks AI-built: few 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 writing signals	+5
AI code-structure 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 12 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 12 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.
