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 28 July 2026; the live site may have changed since.

Smart Calculators Hub is missing several launch fundamentals. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt.

Launched on Product Hunt on July 28, 2026. The site is served through Cloudflare. Our crawler found 8 technologies on this site, covering advertising, CDN, consent tooling, and DNS providers. The stack includes Google Funding Choices, Cloudflare, and Cloudflare DNS.
