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.
Lumen has the basics covered well, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, placeholder text in the legal pages, and no email security records.
Launched on Product Hunt on August 19, 2026. The site is hosted on Netlify. Our crawler found 6 technologies on this site, covering CSS frameworks, frameworks, hosting, and meta-frameworks. The stack includes Next.js, React, and Tailwind CSS.
It's also running the same core stack as 439 other launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
