Portable Text is a JSON-based open specification for structured block content (rich text, images, code, custom types) that can be serialized into any markup language like HTML, Markdown, or XML. The repository hosts the specification along with tooling including a React-based Portable Text Editor and serializers for rendering content in various frameworks.

Use cases

• store rich text as structured JSON instead of HTML strings
• render rich text content as HTML, Markdown, or React components
• build a customizable block content editor in React
• serialize rich text to multiple output formats from one source
• implement real-time collaborative rich text editing
• embed custom content types like images or CTAs inside rich text

When to choose

• you need a framework-agnostic rich text format that serializes to any markup
• you're building a content editing platform or CMS with structured block content
• you want a React editor with custom blocks, styles, and annotations
• you need real-time collaborative editing with rich text annotations

When to avoid

• you just need simple Markdown or HTML storage without structured blocks
• you need a non-React editor without building your own tooling
• your project requires a WYSIWYG editor out of the box with no configuration
