Own this Launch?

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

DevVizor scores well across the board, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: no Permissions-Policy, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 19, 2026. The site is hosted on Amazon.com in the United States. Our crawler found 12 technologies on this site, covering analytics, baas, build tooling, and developer tools. The stack includes Vite, Firebase, and Google Analytics.

Notably, it's on one of the most common stacks we track, shared by 679 launches and more locked down than the typical Product Hunt launch.
