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 May 2026; the live site may have changed since.
PDF Merge has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.
Launched on Product Hunt on May 4, 2026. The site is hosted on UK Internet Service Provider in the United Kingdom, with a domain registered 6 days before launch. Our crawler found 6 technologies on this site, covering DNS providers, business email, web fonts, and frameworks. The stack includes Vue.js, Cloudflare DNS, and Google Fonts.
It's also on one of the most common stacks we track, shared by 249 launches.
