Own this Launch?

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 6 June 2026; the live site may have changed since.

RDF Visualizer is missing several launch fundamentals. What needs work: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on June 6, 2026. The site is hosted on Cloudflare in the United States, with a domain registered in 2025. Our crawler found 8 technologies on this site, covering analytics, CDN, cloud, and DNS providers. The stack includes Amazon Web Services, AWS S3, and Cloudflare.

Notably, it's running the same core stack as 165 other launches.
