Added July 21, 2026 · Last analysed September 1, 2026 · via StackScope Discovery · also on Product Hunt

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 1 September 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.

Lingueez — build a vocabulary that sticks has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.

The site is hosted on GitHub Pages and served through Cloudflare, with a domain registered 3 weeks before launch. Our crawler found 16 technologies on this site, covering directory, CDN, security, and developer tools. The stack includes Brevo, Cloudflare, and Cloudflare Bot Management.

It's also on one of the most common stacks we track, shared by 2,618 launches.
