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 8 July 2026; the live site may have changed since.
WinnerAdSpy looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on July 8, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 3 weeks before launch. We've detected 15 technologies on this site, covering advertising, security, analytics, and CDN. The stack includes Nuxt, Tailwind CSS, and Cloudflare.
It's on a stack we've seen on only 15 launches.
