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 19 August 2026; the live site may have changed since.

LUMO looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on August 19, 2026. The site is hosted on Hostinger and served through Cloudflare, with a domain registered 1 day before launch. We've detected 9 technologies on this site, covering CDN, directory, DNS providers, and business email. The stack includes Apple App Store, Cloudflare, and Cloudflare Bot Management.

It's on one of the most common stacks we track, shared by 1,156 launches.
