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.

CourseFinder — Online Course Directory looks production-ready overall, with complete legal pages and clean crawl signals. Visible gaps: missing several security headers and no email security records.

Launched on Product Hunt on September 1, 2026. The site is hosted on Vercel. We've detected 7 technologies on this site, covering baas, developer tools, web fonts, and hosting. The stack includes Firebase, Google Fonts, and Google Search Console.

It's on one of the most common stacks we track, shared by 4,182 launches.
