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 4 June 2026; the live site may have changed since.
Lessona scores well across the board, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing Permissions-Policy and Content-Security-Policy.
Launched on Product Hunt on June 4, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 3 weeks before launch. We've detected 19 technologies on this site, covering security, advertising, analytics, and auth. The stack includes Clerk, Google, and Next.js.
It's on one of the most common stacks we track, shared by 6,603 launches and more locked down than the typical Product Hunt launch.
