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 15 April 2026; the live site may have changed since.

DevSignal looks production-ready overall, with complete legal pages. Visible gaps: no Content-Security-Policy, no robots.txt or sitemap, and incomplete email security.

Launched on PeerPush on April 15, 2026. The site is hosted on Vercel, with a domain registered 6 weeks before launch. We've detected 6 technologies on this site, covering CSS frameworks, web fonts, frameworks, and hosting. The stack includes Next.js, React, and Tailwind CSS.

It's on one of the most common stacks we track, shared by 10,672 launches and more locked down than the typical PeerPush 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.
