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 15 July 2026; the live site may have changed since.
Calculator Boss -Free Online Calculators has the basics covered well, with complete legal pages and clean crawl signals. What needs work: missing several security headers, tracking cookies set before any opt-in, and no email security records.
Launched on Product Hunt on July 15, 2026. The site is served through Cloudflare, with a domain registered 6 days before launch. Our crawler found 7 technologies on this site, covering analytics, CDN, DNS providers, and web fonts. The stack includes Cloudflare, Cloudflare DNS, and Google Analytics.
