Screenshot of ZipScheduler

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

ZipScheduler ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing Permissions-Policy and Strict-Transport-Security and incomplete email security.

Launched on Product Hunt on June 28, 2026. The site is hosted on Hostinger International Limited in Ukraine, with a domain registered 6 months before launch. The crawl picked up 7 technologies on this site, covering CSS frameworks, business email, frameworks, and hosting. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 227 other launches and tighter on security headers than most Product Hunt launches.
