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 27 July 2026; the live site may have changed since.
FreeWWW Engineering Calculator Suite has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on July 27, 2026. The site is served through Cloudflare, with a domain registered in 1998. Our crawler found 10 technologies on this site, covering analytics, advertising, CDN, and DNS providers. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Web Analytics.
