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 August 2026; the live site may have changed since.

SilentSuite ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and well-configured email security.

Launched on Product Hunt on August 25, 2026. The site is served through Cloudflare. Our crawler found 11 technologies on this site, covering CDN, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.

It's also running the same core stack as 5,474 other launches and tighter on security headers than most Product Hunt launches.
