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 23 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.
Proficienzy - Learn English. has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and no email security records.
Launched on Product Hunt on June 23, 2026. The site is hosted on Vercel, with a domain registered 2 weeks before launch. Our crawler found 13 technologies on this site, covering advertising, analytics, baas, and consent tooling. The stack includes Google Funding Choices, Cloudflare DNS, and Google AdSense.
It's also on one of the most common stacks we track, shared by 4,256 launches.
