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 4 August 2026; the live site may have changed since.

ePub Translator has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers and tracking cookies set before any opt-in.

Launched on Hacker News on August 4, 2026. The site is served through Cloudflare, with a domain registered the day of launch. Our crawler found 12 technologies on this site, covering analytics, backend framework, CDN, and CSS frameworks. The stack includes Stimulus, Tailwind CSS, and Cloudflare.

It's also one of 26 launches on this exact stack.
