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 26 June 2026; the live site may have changed since.

Libre Academy covers some of the launch checklist, with complete legal pages and a thorough launch checklist. Visible gaps: missing several security headers, no robots.txt or sitemap, and no email security records.

Launched on PeerPush on June 26, 2026. The site is hosted on The Constant Company in the United States, with a domain registered 6 weeks before launch. Our crawler found 8 technologies on this site, covering javascript library, analytics, developer tools, and DNS providers. The stack includes Caddy, Gandi DNS, and Google Search Console.
