Schemagic

Visual JSON Schema editor for designing, exploring, and validating schemas in one place.

Added August 17, 2026 · Last analysed August 17, 2026 · via Hacker News

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 17 August 2026; the live site may have changed since.

Schemagic is partway there, with a thorough launch checklist, well-configured email security, and fast page loads. What needs work: missing several security headers and incomplete legal pages.

Launched on Hacker News on August 17, 2026. The site is served through Cloudflare, with a domain registered 5 months before launch. The crawl picked up 11 technologies on this site, covering analytics, javascript library, CDN, and CSS frameworks. The stack includes Tailwind CSS, TanStack Start, and Cloudflare.

For context, it's running the same core stack as 1,020 other launches.
