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 5 August 2026; the live site may have changed since.

Code Rakuda ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: no Content-Security-Policy, tracking cookies set before any opt-in, and no email security records.

Launched on Product Hunt on August 5, 2026. The site is hosted on Firebase App Hosting and served through Fastly, with a domain registered 4 weeks before launch. We've detected 15 technologies on this site, covering auth, analytics, baas, and CDN. The stack includes Google Identity Platform, Google Sign-In, and Next.js.

It's on a stack we've seen on only 2 launches and tighter on security headers than most Product Hunt launches.
