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 June 2026; the live site may have changed since.

Vivix has the basics covered well, with a thorough launch checklist, fast page loads, and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and analytics without a consent banner.

Launched on Hacker News on June 3, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 7 weeks before launch. Our crawler found 6 technologies on this site, covering analytics, build tooling, CDN, and DNS providers. The stack includes Vite, Cloudflare, and Cloudflare DNS.

Notably, it's running the same core stack as 629 other launches.
