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 June 2026; the live site may have changed since.

Interactive Sudoku Technique Docs still has work before launch. Main gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on June 17, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 5 months before launch. The crawl picked up 9 technologies on this site, covering advertising, analytics, CDN, and consent tooling. The stack includes Google Funding Choices, Vue.js, and Cloudflare.

For context, it's one of 82 launches on this exact stack.
