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.
Seiless covers some of the launch checklist, with complete legal pages. Worth fixing first: missing several security headers, no robots.txt or sitemap, and incomplete email security.
Launched on Product Hunt on June 18, 2026. The site is hosted on Amazon.com in the United States. Our crawler found 6 technologies on this site, covering DNS providers, business email, frameworks, and hosting. The stack includes Next.js, React, and HSTS.
Notably, it's running the same core stack as 1,583 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.
