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 9 June 2026; the live site may have changed since.
SiteBlocker V4 scores well across the board, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: no sitemap, analytics without a consent banner, and incomplete email security.
Launched on Product Hunt on June 9, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2025. Our crawler found 16 technologies on this site, covering analytics, baas, chat widgets, and CSS frameworks. The stack includes Astro, Tailwind CSS, and Crisp.
Notably, it's one of 79 launches on this exact stack and more locked down than the typical Product Hunt launch.
