Screenshot of JSON Schema Multi-Generator

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 June 2026; the live site may have changed since.

JSON Schema Multi-Generator has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers, analytics without a consent banner, and incomplete email security.

Launched on Product Hunt on June 9, 2026. The site is hosted on Fastly in the United States. Our crawler found 6 technologies on this site, covering analytics, CDN, DNS providers, and business email. The stack includes Fastly, GitHub Pages, and Google Analytics.

Notably, it's on one of the most common stacks we track, shared by 1,019 launches.
