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 15 July 2026; the live site may have changed since.

numasims — Virtual Phone Numbers has the basics covered well, with complete legal pages, well-configured email security, and clean crawl signals. What needs work: missing several security headers.

Launched on Product Hunt on July 15, 2026. The site is served through Cloudflare, with a domain registered 2 weeks before launch. Our crawler found 12 technologies on this site, covering auth, CDN, DNS providers, and email forwarding. The stack includes Auth.js, Next.js, and React.

It's also running the same core stack as 743 other launches.
