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 Sieve ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: tracking cookies set before any opt-in and incomplete email security.
Launched on Product Hunt on August 20, 2026. The site is hosted on The Constant Company in the United States, with a domain registered 2 weeks before launch. We've detected 15 technologies on this site, covering analytics, ui library, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
It's running the same core stack as 5,206 other launches and tighter on security headers than most Product Hunt 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.
