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 April 2026; the live site may have changed since.

PDFClarify is partway there, with complete legal pages and fast page loads. Visible gaps: missing several security headers, no sitemap, and no email security records.

Launched on Product Hunt on April 7, 2026. The site is served through Cloudflare. The crawl picked up 6 technologies on this site, covering CDN, DNS providers, web fonts, and package cdn. The stack includes Cloudflare, Cloudflare DNS, and Google Fonts.
