A lightweight, extensible rich text editor toolkit built on ProseMirror. Framework-agnostic headless core with first-class Angular, React, Vue, and Vanilla wrappers. Use it headless with vanilla JS/TS, add the built-in toolbar and theme, or drop in ready-made framework components. Fully tree-shakeable, import only what you use, unused extensions are stripped from your bundle.
