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

DSA Pattern Visualizer has the basics covered well, with a thorough launch checklist and clean crawl signals. Worth fixing first: no Content-Security-Policy, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on July 1, 2026. The site is served through Cloudflare, with a domain registered 1 week before launch. Our crawler found 9 technologies on this site, covering analytics, CDN, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Cloudflare, and Cloudflare Web Analytics.

It's also running the same core stack as 5,297 other launches and tighter on security headers than most Product Hunt launches.
