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

Random Number Generator is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and no email security records.

Launched on PeerPush on June 19, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 4 weeks before launch. The crawl picked up 6 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.

For context, it's on one of the most common stacks we track, shared by 1,150 launches.
