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 23 July 2026; the live site may have changed since.
Speed of Light (PRO) scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on July 23, 2026. The site is served through Cloudflare. We've detected 8 technologies on this site, covering analytics, CDN, CMS, and DNS providers. The stack includes WordPress, Cloudflare, and Cloudflare DNS.
