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 10 August 2026; the live site may have changed since.
20PDF is partway there, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.
Launched on Product Hunt on August 10, 2026. The site is served through Cloudflare. The crawl picked up 11 technologies on this site, covering security, analytics, CDN, and cloud. The stack includes Tailwind CSS, Amazon Web Services, and Cloudflare.
For context, it's running the same core stack as 6,830 other launches.
