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

Numbergram covers some of the launch checklist, with fast page loads and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Hacker News on July 11, 2026. The site is served through Cloudflare, with a domain registered in 2022. Our crawler found 5 technologies on this site, covering CDN, DNS providers, email forwarding, and meta-frameworks. The stack includes Gatsby, Cloudflare, and Cloudflare DNS.

It's also a rare Gatsby sighting, just 32 in our data.
