What Slate is

Slate is a free, MIT-licensed framework for developers building customizable rich text editors for web applications. It is a pluggable contenteditable implementation built on React, with a plugin-first architecture and schema-less core. Its nested, recursive document tree can represent structures such as tables and nested block quotes. Documentation examples cover rich text, Markdown previews, inline nodes, images, tables, and pasted HTML. The data model is designed for collaborative editing, and the guide demonstrates multiplayer editing with Yjs and a backend communication provider. Extensions listed by the project include Plate, slate-yjs, and slate-collaborative. Slate supports React, Angular, and Vue 3 projects, with structured content, table editing, real-time collaboration, image handling, and custom rich-media components. Developers should note that Slate is in beta, some APIs may change in breaking ways, and Internet Explorer is unsupported. Its TypeScript approach supports one document model at a time.

Who it suits

Slate suits developers who need a customizable editor inside a web application. It is especially relevant for projects requiring structured documents, collaboration, tables, or custom media rendering.

What it does well

What to know first
