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

SimVault ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers and incomplete email security.

Launched on Product Hunt on June 20, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 1 week before launch. We've detected 7 technologies on this site, covering CDN, CSS frameworks, DNS providers, and email forwarding. The stack includes Astro, Tailwind CSS, and Cloudflare.

It's running the same core stack as 276 other launches.
