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 August 2026; the live site may have changed since.

NobodyCalls looks production-ready overall, with a thorough launch checklist. What needs work: no Content-Security-Policy, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on August 1, 2026. The site is served through Cloudflare, with a domain registered in 2018. We've detected 7 technologies on this site, covering CDN, security, directory, and frameworks. The stack includes Next.js, React, and Cloudflare.

It's running the same core stack as 904 other launches and tighter on security headers than most Product Hunt launches.
