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 30 August 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.

Crux — Unified Developer Collaboration is partway there, with a thorough launch checklist, fast page loads, and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on August 30, 2026. The site is served through Cloudflare. The crawl picked up 4 technologies on this site, covering CDN, CSS frameworks, developer tools, and javascript library. The stack includes Tailwind CSS, Anime.js, and Cloudflare.

For context, it's on one of the most common stacks we track, shared by 7,540 launches.
