StackScope records what new websites are built with, the week they launch. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We crawled this one for its tech stack and scored it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 26 June 2026; the live site may have changed since.

Every technology below links to its own page: which other new sites launched with it. Vendors and agencies watch those pages with Stackdar and hear about new adopters the week they ship, from £15 a month.

SeaOtter.ai is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.

Launched on Product Hunt on June 26, 2026. The site is hosted on Google Cloud, with a domain registered 11 months before launch. The crawl picked up 12 technologies on this site, covering analytics, communication, consent tooling, and DNS providers. The stack includes Google, Next.js, and React.

For context, it's one of 44 launches on this exact stack.
