ButterCMS

ButterCMS is a headless CMS that provides tools for content creation, management, and distribution. While it doesn't directly offer a public-facing publishing platform like Medium, it provides the underlying infrastructure that enables such a platform to be built. It features a rich text editor, allows for content scheduling and previewing (which implies reader engagement metrics for internal use), and supports collaboration and multi-site management, which can be analogous to publication management. It also has features like user profiles (for content creators/editors), tags, and social sharing capabilities. The core difference is that ButterCMS is a backend content management system, not a direct publishing platform for end-users.
