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

PDF Editor Pro — Edit PDF Files Free, ships with the basics, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on July 18, 2026. The site is hosted on Netlify. We've detected 13 technologies on this site, covering javascript library, ui library, analytics, and CSS frameworks. The stack includes Tailwind CSS, Google Analytics, and Google Search Console.
