ProseMirror is a JavaScript toolkit for building rich-text WYSIWYG editors on the web, based on contentEditable with support for custom document schemas and collaborative editing. It is a modular, plugin-based library distributed as separate npm modules rather than a ready-to-use editor.

Use cases

• build a rich-text editor for a web app
• add collaborative real-time editing to a document editor
• create a structured content editor with custom document schemas
• build a markdown-like editor with a WYSIWYG interface
• embed a semantic rich-text editor in a CMS
• implement a comment or note editor with constrained formatting

When to choose

• you need fine-grained control over document structure and semantics
• you want real-time collaborative editing support
• you are building a custom editor rather than wanting an out-of-the-box one
• you need a modular, extensible editing toolkit for the browser

When to avoid

• you just need a simple textarea or basic markdown input
• you want a fully prebuilt editor with minimal configuration
• you are building a native mobile or desktop app without a web view
