Substance is a JavaScript library for building web-based content editing experiences. It provides building blocks for creating custom text editors and web-based publishing systems.

Use cases

  • build a custom rich text editor in the browser
  • create a web-based publishing platform
  • add structured content editing with annotations to a web app
  • implement collaborative document editing UI
  • edit HTML or XML documents in the browser

When to choose

  • you need fine-grained control over a custom web text editor
  • you are building a publishing or annotation-focused editing tool
  • you want a library of editor building blocks rather than a turnkey editor

When to avoid

  • you just need a ready-made WYSIWYG editor with minimal setup
  • you need a native desktop or mobile editor
  • you want a heavily maintained project with a large active community
