SilverStripe

SilverStripe is an open-source CMS and framework. While it provides tools for content creation and management, it is not primarily a publishing platform for individual writers to monetize content like Medium. It offers a rich text editor, user profiles, and tagging, but lacks explicit features for content monetization based on reading time or a built-in recommendation engine for content discovery in the same vein as Medium. It's more of a foundational tool for building websites rather than a direct content distribution platform.
