Tiptap

Tiptap is a developer toolkit for building content editing and real-time collaboration tools. It offers a headless rich text editor framework with various extensions, including collaboration features like real-time presence and comments. While it provides the core components for a rich text editor and community feedback tools (comments), it is a foundational tool for developers to build publishing platforms, rather than a complete end-user publishing platform like Medium. It lacks direct features for content distribution, recommendation engines, or built-in monetization models for writers, which are core to Medium's value proposition.
