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

DevNex scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: incomplete email security.

Launched on Product Hunt on August 26, 2026. The site is hosted on Vercel, with a domain registered 2 days before launch. The crawl picked up 10 technologies on this site, covering analytics, consent tooling, CSS frameworks, and DNS providers. The stack includes Google, Next.js, and React.

For context, it's on one of the most common stacks we track, shared by 14,159 launches and more locked down than the typical Product Hunt launch.
