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 4 June 2026; the live site may have changed since.
kaku.so is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers and no sitemap.
Launched on Product Hunt on June 4, 2026. The site is hosted on Datacamp Limited in the United Kingdom, with a domain registered 10 months before launch. The crawl picked up 7 technologies on this site, covering business email, CDN, CSS frameworks, and DNS providers. The stack includes Astro, Tailwind CSS, and Bunny CDN.
For context, it's on one of the most common stacks we track, shared by 205 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.
