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 16 June 2026; the live site may have changed since.

ClaudePractice scores well across the board, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: no Content-Security-Policy and no email security records.

Launched on Product Hunt on June 16, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 3 months before launch. We've detected 13 technologies on this site, covering security, analytics, auth, and CDN. The stack includes Clerk, Google, and Next.js.

It's on one of the most common stacks we track, shared by 7,717 launches and more locked down than the typical Product Hunt launch.
