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

LeadSonar looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on May 13, 2026. The site is hosted on Netlify and served through Cloudflare. We've detected 13 technologies on this site, covering security, CDN, CSS frameworks, and DNS providers. The stack includes React, Tailwind CSS, and Beehiiv.

It's one of just 17 launches we've crawled on this exact stack.
