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 April 2026; the live site may have changed since.

Knowb4usign.com ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.

Launched on Product Hunt on April 28, 2026. The site is served through Cloudflare, with a domain registered 7 weeks before launch. Our crawler found 8 technologies on this site, covering CDN, DNS providers, transactional email, and web fonts. The stack includes Next.js, React, and Cloudflare.

It's also running the same core stack as 762 other launches.
