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 18 August 2026; the live site may have changed since.

SacredCal is missing several launch fundamentals. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on August 18, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered 2 weeks before launch. Our crawler found 8 technologies on this site, covering CDN, DNS providers, business email, and email forwarding. The stack includes Next.js, React, and Fastly.

It's also one of just 18 launches we've crawled on this exact stack.
