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 30 April 2026; the live site may have changed since.

Mdview.io has the basics covered well, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on April 30, 2026. The site is hosted on Fly.io and served through Cloudflare. Our crawler found 10 technologies on this site, covering analytics, auth, backend framework, and CDN. The stack includes Clerk, Cloudflare, and Cloudflare Bot Management.

It's also one of 89 launches on this exact stack.
