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 28 May 2026; the live site may have changed since.

Offline Survival Kit scores highly overall, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: no Content-Security-Policy, no sitemap, and tracking cookies set before any opt-in.

Launched on Product Hunt on May 28, 2026. The site is hosted on Vercel, with a domain registered 2 weeks before launch. We've detected 7 technologies on this site, covering mobile, analytics, DNS providers, and business email. The stack includes Apple App Store, Google Analytics, and Google Play.

It's on one of the most common stacks we track, shared by 2,956 launches and more locked down than the typical Product Hunt launch.
