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 25 August 2026; the live site may have changed since.
NextGenUp looks production-ready overall, with a thorough launch checklist and clean crawl signals. What needs work: missing Content-Security-Policy and Strict-Transport-Security, incomplete legal pages, and incomplete email security.
Launched on Product Hunt on August 25, 2026. The site is served through Cloudflare. We've detected 6 technologies on this site, covering CDN, DNS providers, email forwarding, and web fonts. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Email Routing.
It's tighter on security headers than most Product Hunt launches.
