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 14 July 2026; the live site may have changed since.
Kaku scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: no Permissions-Policy, tracking cookies set before any opt-in, and no email security records.
Launched on Product Hunt on July 14, 2026. The site is hosted on Vercel and served through Cloudflare. The crawl picked up 13 technologies on this site, covering analytics, security, CDN, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.
For context, it's on one of the most common stacks we track, shared by 10,281 launches and more locked down than the typical Product Hunt launch.
