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 12 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.
Qursor ships with the basics, with a thorough launch checklist. What needs work: missing several security headers, incomplete legal pages, and no sitemap.
Launched on Product Hunt on June 12, 2026. The site is served through Cloudflare. We've detected 14 technologies on this site, covering web fonts, seo, analytics, and auth. The stack includes Astro, Clerk, and Tailwind CSS.
It's running the same core stack as 839 other launches.
