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.

BlockDex is largely in shape, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers and incomplete email security.

Launched on Hacker News on August 21, 2026. The site is hosted on Vercel, with a domain registered 8 weeks before launch. The crawl picked up 7 technologies on this site, covering analytics, frameworks, hosting, and javascript library. The stack includes Next.js, React, and HSTS.

For context, it's running the same core stack as 3,096 other launches.
