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

Lumio has the basics covered well, with complete legal pages and clean crawl signals. What needs work: missing several security headers and incomplete email security.

Launched on Product Hunt on June 24, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 6 weeks before launch. Our crawler found 6 technologies on this site, covering CSS frameworks, web fonts, frameworks, and hosting. The stack includes Next.js, React, and Tailwind CSS.

Notably, it's running the same core stack as 8,456 other launches.
