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

HenryLearns looks production-ready overall, with complete legal pages. Main gaps: missing several security headers, no sitemap, and no email security records.

Launched on Product Hunt on August 21, 2026. The site is served through Cloudflare. We've detected 7 technologies on this site, covering CDN, CSS frameworks, DNS providers, and frameworks. The stack includes Next.js, React, and Tailwind CSS.
