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 27 August 2026; the live site may have changed since.

ScanDue: Expiry Tracker looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and incomplete email security.

Launched on Product Hunt on August 27, 2026. The site is hosted on Vercel, with a domain registered 5 months before launch. We've detected 6 technologies on this site, covering CSS frameworks, frameworks, hosting, and javascript library. The stack includes Next.js, React, and Tailwind CSS.

It's running the same core stack as 14,273 other launches.
