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

PDFSwift ships with the basics, with a thorough launch checklist and fast page loads. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt.

Launched on Product Hunt on June 20, 2026. The site is hosted on Hostinger International Limited in Ukraine, with a domain registered the day of launch. We've detected 7 technologies on this site, covering package cdn, business email, hosting, and protocol. The stack includes cdnjs, Google Search Console, and Hostinger.

It's on one of the most common stacks we track, shared by 602 launches.
