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 11 July 2026; the live site may have changed since.
PD Measure scores highly overall, with complete legal pages and a thorough launch checklist. Visible gaps: no Strict-Transport-Security, no sitemap, and incomplete email security.
Launched on Product Hunt on July 11, 2026. The site is served through Cloudflare, with a domain registered 1 week before launch. The crawl picked up 10 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Astro, Tailwind CSS, and Cloudflare.
For context, it's on one of the most common stacks we track, shared by 418 launches and more locked down than the typical Product Hunt launch.
