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 June 2026; the live site may have changed since.

Lumi Academy is largely in shape, with a thorough launch checklist, fast page loads, and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on June 16, 2026. The site is hosted on Fastly in the United States. The crawl picked up 8 technologies on this site, covering baas, CDN, web fonts, and hosting. The stack includes Fastly, Firebase, and Firebase Hosting.

For context, it's one of 61 launches on this exact stack.
