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 26 May 2026; the live site may have changed since.

NexaBrief still has work before launch. Main gaps: no Permissions-Policy, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on May 26, 2026. The site is hosted on AS132203-108 - Shenzhen Tencent Computer Systems Company Limited in Singapore. The crawl picked up 3 technologies on this site, covering protocol, security, and servers. The stack includes Caddy, HSTS, and HTTP/3.

For context, it's more locked down than the typical Product Hunt launch.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
