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 27 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.
RetroPlayOnline looks production-ready overall, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers.
Launched on Product Hunt on June 27, 2026. The site is served through Cloudflare, with a domain registered 2 weeks before launch. We've detected 15 technologies on this site, covering analytics, CDN, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Ahrefs, and cdnjs.
It's running the same core stack as 7,721 other launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
