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 26 May 2026; the live site may have changed since.

CalcNest AI ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: tracking cookies set before any opt-in and incomplete email security.

Launched on Product Hunt on May 26, 2026. The site is hosted on Netlify and served through Cloudflare, with a domain registered 6 weeks before launch. The crawl picked up 14 technologies on this site, covering security, advertising, affiliate, and analytics. The stack includes Cloudflare, Cloudflare Bot Management, and Google Ads.

For context, it's running the same core stack as 1,571 other launches and tighter on security headers than most Product Hunt launches.
