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

Markdown Viewer looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on July 18, 2026. The site is served through Cloudflare. We've detected 10 technologies on this site, covering ui library, analytics, CDN, and DNS providers. The stack includes Next.js, React, and Cloudflare.

It's running the same core stack as 762 other launches.
