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

Zalfa looks production-ready overall, with a complete set of security headers and clean crawl signals. Main gaps: incomplete legal pages and no email security records.

Launched on Product Hunt on July 3, 2026. The site is hosted on Vercel. We've detected 11 technologies on this site, covering advertising, analytics, auth, and captcha. The stack includes Google Sign-In, Next.js, and React.

It's on one of the most common stacks we track, shared by 9,207 launches and more locked down than the typical Product Hunt launch.
