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 28 April 2026; the live site may have changed since.
QuackPDFTools is largely in shape, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and no email security records.
Launched on Product Hunt on April 28, 2026. The site is served through Cloudflare, with a domain registered 6 days before launch. The crawl picked up 8 technologies on this site, covering seo, analytics, CDN, and DNS providers. The stack includes Bing Webmaster, Cloudflare, and Cloudflare DNS.
