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 6 July 2026; the live site may have changed since.

Riddlo ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: no Permissions-Policy and no sitemap.

Launched on Product Hunt on July 6, 2026. The site is hosted on DigitalOcean in the United States. We've detected 16 technologies on this site, covering seo, ui library, analytics, and auth. The stack includes Auth.js, Next.js, and React.

It's running the same core stack as 3,358 other launches and tighter on security headers than most Product Hunt launches.
