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

Nemotron 3 Ultra by NVIDIA has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers and no sitemap.

Launched on Product Hunt on June 5, 2026. The site is hosted on Akamai International B.V. in the Netherlands, with a domain registered in 1993. Our crawler found 24 technologies on this site, covering analytics, CDN, marketing, and package cdn. The stack includes OneTrust, WordPress, and 6sense.

Notably, it's one of only 3 launches we've crawled running Pantheon.
