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.
Zernio WhatsApp API has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.
Launched on Product Hunt on June 19, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 10 months before launch. Our crawler found 26 technologies on this site, covering analytics, advertising, security, and seo. The stack includes Auth.js, Google, and Next.js.
Notably, it's on one of the most common stacks we track, shared by 7,958 launches.
