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
