StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score 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.
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 hosted on Cloudflare in the United States, 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 5,148 other launches.
