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 21 July 2026; the live site may have changed since.

LUFS Converter Pro scores highly overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: no Content-Security-Policy.

Launched on Product Hunt on July 21, 2026. The site is hosted on Vodafone GmbH in Germany, with a domain registered in 2013. Our crawler found 2 technologies on this site, covering security and servers. The stack includes HSTS and OpenResty.

It's also more locked down than the typical Product Hunt launch.
