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

Fact0 looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers and no email security records.

Launched on Product Hunt on June 10, 2026. The site is hosted on Amazon.com in the United States. We've detected 10 technologies on this site, covering CSS frameworks, DNS providers, business email, and transactional email. The stack includes Next.js, React, and Tailwind CSS.

It's running the same core stack as 7,154 other launches.
