Own this Launch?

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 June 2026; the live site may have changed since.

EPUB Reader has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on June 19, 2026. The site is hosted on Hostinger International Limited in Germany, with a domain registered in 2025. Our crawler found 5 technologies on this site, covering business email, hosting, package cdn, and protocol. The stack includes Hostinger, Hostinger Email, and HTTP/3.

Notably, it's on one of the most common stacks we track, shared by 539 launches.
