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 24 April 2026; the live site may have changed since.
ZeroCloudPDF is partway there, with clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.
Launched on Product Hunt on April 24, 2026. The site is served through Fastly, with a domain registered 3 weeks before launch. The crawl picked up 10 technologies on this site, covering analytics, baas, CDN, and DNS providers. The stack includes cdnjs, Cloudflare DNS, and Cloudflare Email Routing.
