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 30 July 2026; the live site may have changed since.
StringScales ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: tracking cookies set before any opt-in and incomplete email security.
Launched on Product Hunt on July 30, 2026. The site is served through Cloudflare, with a domain registered in 2024. We've detected 15 technologies on this site, covering analytics, business email, security, and CDN. The stack includes Next.js, React, and Tailwind CSS.
It's running the same core stack as 4,409 other launches and tighter on security headers than most Product Hunt launches.
