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 18 August 2026; the live site may have changed since.

BookKraft AI scores highly overall, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing X-Frame-Options and Permissions-Policy and incomplete email security.

Launched on Product Hunt on August 18, 2026. The site is served through Cloudflare, with a domain registered 5 months before launch. We've detected 22 technologies on this site, covering analytics, directory, security, and seo. The stack includes Google, Next.js, and React.

It's on one of the most common stacks we track, shared by 1,089 launches and more locked down than the typical Product Hunt launch.
