JavaScript vs. Plate vs. Roy vs. Untitled UI Comparison Chart

​Plate is a rich-text editor framework for React, designed to simplify complex text editing needs. Built with Slate.js and TypeScript, it offers a highly customizable and extensible editing experience. Plate provides a wide range of plugin packages that enhance the behavior, hooks, serialization, normalization, and other features of the editor. These plugins are "headless," meaning they are unstyled by default, allowing developers to style them as needed. It includes state management with Zustand stores, custom hotkeys, API methods, and transforms accessible through editor.api and editor.transforms. Plate also offers unstyled and accessible components based on Radix UI, serving as the foundation for building high-quality design systems. For those seeking a visually appealing interface, Plate provides pre-built styled components based on shadcn/ui, which can be customized to create a unique, accessible, and visually pleasing user interface.
