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

Lumen v2 looks production-ready overall, with complete legal pages and clean crawl signals. What needs work: missing several security headers and no email security records.

Launched on Product Hunt on August 20, 2026. The site is hosted on Netlify. We've detected 6 technologies on this site, covering CSS frameworks, frameworks, hosting, and meta-frameworks. The stack includes Next.js, React, and Tailwind CSS.

It's running the same core stack as 443 other launches.
