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.

Free Reverse Sales Tax Calculator 2026 ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Strict-Transport-Security and incomplete email security.

Launched on PeerPush on June 16, 2026. The site is hosted on Hostinger International Limited in Ukraine. The crawl picked up 8 technologies on this site, covering analytics, consent tooling, CSS frameworks, and business email. The stack includes Google, Tailwind CSS, and Google Analytics.

For context, it's running the same core stack as 122 other launches and tighter on security headers than most PeerPush launches.
