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 2 July 2026; the live site may have changed since.

Eduninja looks production-ready overall, 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 July 2, 2026. The site is hosted on Hangzhou Alibaba Advertising Co. in China, with a domain registered in 2023. We've detected 7 technologies on this site, covering CSS frameworks, DNS providers, business email, and frameworks. The stack includes Tailwind CSS, Vue.js, and Alibaba Cloud.

It's on one of the most common stacks we track, shared by 217 launches.
