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 April 2026; the live site may have changed since.

Megacub scores highly overall, with complete legal pages and a thorough launch checklist. Visible gaps: missing Permissions-Policy and Content-Security-Policy, no sitemap, and tracking cookies set before any opt-in.

Launched on Product Hunt on April 17, 2026. The site is hosted on Render and served through Cloudflare, with a domain registered 7 weeks before launch. Our crawler found 12 technologies on this site, covering analytics, backend framework, CDN, and developer tools. The stack includes Cloudflare, Cloudflare DNS, and Google Analytics.

It's also on one of the most common stacks we track, shared by 450 launches and more locked down than the typical Product Hunt launch.
