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 June 2026; the live site may have changed since.

Merge JSON scores well across the board, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and no email security records.

Launched on Product Hunt on June 15, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 1 day before launch. Our crawler found 7 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Astro, Tailwind CSS, and Cloudflare.

Notably, it's on one of the most common stacks we track, shared by 245 launches.

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.
