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

AddvCard ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing several security headers and tracking cookies set before any opt-in.

Launched on Product Hunt on June 23, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 7 months before launch. Our crawler found 12 technologies on this site, covering CDN, analytics, DNS providers, and business email. The stack includes Cloudflare, Cloudflare DNS, and Fastly.
