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 2 August 2026; the live site may have changed since.
CalcMaster scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing Content-Security-Policy and Strict-Transport-Security and incomplete email security.
Launched on Product Hunt on August 2, 2026. The site is served through Cloudflare, with a domain registered 1 day before launch. We've detected 17 technologies on this site, covering advertising, ui library, analytics, and APIs. The stack includes Google Funding Choices, Tailwind CSS, and Cloudflare.
It's on one of the most common stacks we track, shared by 6,580 launches and more locked down than the typical Product Hunt launch.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
