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

JavaScript tutorial is largely in shape. Visible gaps: missing Permissions-Policy and Strict-Transport-Security, incomplete legal pages, and no robots.txt.

Launched on Hacker News on June 24, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 8 months before launch. The crawl picked up 6 technologies on this site, covering advertising, CDN, DNS providers, and business email. The stack includes Brave Rewards, Cloudflare, and Cloudflare DNS.

For context, it's more locked down than the typical Hacker News launch.
