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

The Virtual OS Museum ships with the basics, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on June 8, 2026. The site is hosted on Google LLC in the United States. We've detected 4 technologies on this site, covering DNS providers, web fonts, icon font, and package cdn. The stack includes Cloudflare DNS, Font Awesome, and Google Fonts.
