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 22 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.
Prompt Smartly AI ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: no Content-Security-Policy and no email security records.
Launched on Product Hunt on June 22, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered 1 week before launch. Our crawler found 12 technologies on this site, covering security, auth, backend framework, and CDN. The stack includes Clerk, Cloudflare, and Cloudflare Bot Management.
It's also running the same core stack as 668 other launches and tighter on security headers than most Product Hunt launches.
