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

Dungeon Mastron is largely in shape, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing Permissions-Policy and Content-Security-Policy, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on July 11, 2026. The site is hosted on Vercel, with a domain registered 6 months before launch. The crawl picked up 9 technologies on this site, covering analytics, DNS providers, business email, and web fonts. The stack includes Ahrefs, Google Analytics, and Google Fonts.

For context, it's running the same core stack as 2,744 other launches and tighter on security headers than most Product Hunt launches.
