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 9 May 2026; the live site may have changed since.

Zoju scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: tracking cookies set before any opt-in and incomplete email security.

Launched on Product Hunt on May 9, 2026. The site is hosted on Vercel, with a domain registered 8 weeks before launch. The crawl picked up 20 technologies on this site, covering analytics, ai api, baas, and captcha. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 10,662 launches and more locked down than the typical Product Hunt launch.
