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 18 June 2026; the live site may have changed since.
Vivo looks production-ready overall, with complete legal pages, well-configured email security, and clean crawl signals. Visible gaps: missing several security headers and tracking cookies set before any opt-in.
Launched on Product Hunt on June 18, 2026. The site is hosted on Zenlayer Inc in Singapore, with a domain registered in 1998. We've detected 14 technologies on this site, covering analytics, SaaS tooling, advertising, and ai service. The stack includes jQuery, Contentsquare, and DNSPod.
It's on one of the most common stacks we track, shared by 119 launches.
