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

Loan Interest and Repayment Calculator still has work before launch. Visible gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on July 18, 2026. The site is hosted on Google Cloud, with a domain registered 2 days before launch. The crawl picked up 11 technologies on this site, covering ui library, AI builders, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Google Cloud, and Google Fonts.

For context, it's on one of the most common stacks we track, shared by 608 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.
