Lexxy is a modern rich text editor for Ruby on Rails, built as a custom element on top of Meta's Lexical editor framework by 37signals. It acts as a drop-in replacement for Trix in Action Text, offering clean HTML semantics, Markdown shortcuts, real-time code highlighting, attachment previews, and configurable prompts such as @mentions.

Use cases

• add a rich text editor to a Rails app
• replace Trix with a better editor in Action Text
• wysiwyg editor with markdown shortcuts and clean HTML output
• rich text editor with real-time code syntax highlighting
• implement @mentions or slash-commands in a Rails text area
• let users attach and preview PDFs and videos inside an editor
• editor that generates the canonical HTML Action Text expects

When to choose

• you are building a Rails application and want a drop-in editor for Action Text with zero configuration
• you need semantic HTML output with real <p> tags instead of markup soup
• you want mentions, interactive prompts, tables, galleries, and attachment previews out of the box
• you prefer vanilla JavaScript and CSS that is easy to customize and extend

When to avoid

• your stack is not Ruby on Rails - the deepest value comes from Action Text and Active Storage integration
• you need a frozen, guaranteed-stable extension API - the extensions API is experimental and may change without deprecation
• you want a general-purpose Lexical wrapper for React or other JS frameworks - using Lexical directly may fit better
• you only need plain markdown editing without rich text features - a simpler markdown editor may suffice
