Trix is a WYSIWYG rich text editor for web applications, built by 37signals as a JavaScript custom element. It uses its own internal document model rather than relying on contenteditable's execCommand APIs, producing consistent HTML output with support for embedded attachments.

Use cases

• add a rich text editor to a web app for writing messages and comments
• let users compose formatted articles or lists in the browser
• embed a WYSIWYG editor with attachment support in a form
• avoid cross-browser contenteditable inconsistencies in a text editor
• build a comment box with bold, italic, and list formatting
• integrate a rich text editor into a Rails or any JavaScript web application

When to choose

• you need a dependable, production-proven WYSIWYG editor for everyday writing like messages, comments, and articles
• you want consistent, terse HTML output across all evergreen browsers
• you prefer a web-standards-based custom element that works with any bundler or framework
• you need built-in support for embedded attachments

When to avoid

• you need complex document editing like tables, collaborative editing, or fine-grained layout control
• you want a fully customizable editor architecture with a plugin ecosystem (consider ProseMirror or Slate)
• you need a plain markdown or code editor rather than WYSIWYG formatting
