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 20 August 2026; the live site may have changed since.

Flux is largely in shape, 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 August 20, 2026. The site is hosted on Vercel, with a domain registered 4 days before launch. The crawl picked up 9 technologies on this site, covering CSS frameworks, DNS providers, transactional email, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 13,623 other launches.
