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

Lumina is largely in shape, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 18, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 6 months before launch. The crawl picked up 14 technologies on this site, covering analytics, CDN, consent tooling, and CSS frameworks. The stack includes Alpine.js, Google, and Tailwind CSS.

For context, it's one of 40 launches on this exact stack.
