Sage

A living, evidence-based picture of how your child learns — turned into a clear plan for what comes next.

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

Sage ships with the basics, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 9, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2025. We've detected 8 technologies on this site, covering transactional email, CDN, cloud, and DNS providers. The stack includes Amazon SES, Amazon Web Services, and AWS CloudFront.

It's on one of the most common stacks we track, shared by 172 launches.
