Screenshot of Notify Customers

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 1 May 2026; the live site may have changed since.

Notify Customers scores highly overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing Permissions-Policy and Content-Security-Policy and tracking cookies set before any opt-in.

Launched on Product Hunt on May 1, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2017. The crawl picked up 10 technologies on this site, covering analytics, chat widgets, DNS providers, and business email. The stack includes Google Analytics, Google Domains DNS, and Google Fonts.

For context, it's more locked down than the typical Product Hunt launch.
