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 17 August 2026; the live site may have changed since.
PercentageCalcs 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 no email security records.
Launched on Product Hunt on August 17, 2026. The site is served through Cloudflare, with a domain registered 2 days before launch. Our crawler found 12 technologies on this site, covering analytics, javascript library, CDN, and CSS frameworks. The stack includes Tailwind CSS, TanStack Start, and Cloudflare.
It's also running the same core stack as 1,020 other launches.

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.
