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 25 July 2026; the live site may have changed since.

Gantra ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Permissions-Policy and no email security records.

Launched on Product Hunt on July 25, 2026. The site is hosted on Contabo GmbH in Germany, with a domain registered 3 days before launch. We've detected 7 technologies on this site, covering CSS frameworks, DNS providers, web fonts, and meta-frameworks. The stack includes Astro, Tailwind CSS, and Dyna-NS.

It's running the same core stack as 517 other launches and tighter on security headers than most Product Hunt launches.
