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

Mdview.io covers some of the launch checklist, with a thorough launch checklist, fast page loads, and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on April 15, 2026. The site is hosted on Fly.io in the United States. Our crawler found 10 technologies on this site, covering analytics, auth, build tooling, and CDN. The stack includes Clerk, Express, and Vite.

Notably, it's on a stack we've seen on only 3 launches.
