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 June 2026; the live site may have changed since.

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

Launched on Product Hunt on June 30, 2026. The site is hosted on Vercel, with a domain registered 8 weeks before launch. Our crawler found 11 technologies on this site, covering analytics, auth, developer tools, and DNS providers. The stack includes Google Sign-In, Google Fonts, and Google Search Console.

It's also on one of the most common stacks we track, shared by 2,435 launches.
