When developers need a rich textbox or HTML editor, the usual choices often come with tradeoffs: expensive licenses, heavy dependencies, complicated setup, limited customization, or a toolbar that only covers the basics. rt-native.js found on NPM and its .NET Blazor wrapper, RTBlazorfied found on NuGet, provide one of the most mature, free, and feature-rich HTML editors available that can be added to any modern web application without turning the editor into a project.

A Feature Rich Experience
The strongest argument for rt-native and RTBlazorfied is that it provides nearly everything most developers expect from a modern rich textbox editor. The toolbar supports common formatting including:
| Feature | Category |
|---|---|
| Bold | Text formatting |
| Italic | Text formatting |
| Underline | Text formatting |
| Strikethrough | Text formatting |
| Subscript | Text formatting |
| Superscript | Text formatting |
| Inline code | Code formatting |
| Text color | Text styling |
| Text background color | Text styling |
| Alignment | Paragraph formatting |
| Ordered lists | Lists |
| Unordered lists | Lists |
| Indentation | Paragraph formatting |
| Links | Content insertion |
| Images | Media insertion |
| Uploaded images | Media insertion |
| Block quotes | Block formatting |
| Code blocks | Code formatting |
| Tables | Content structure |
| Embedded media | Media insertion |
| Video | Media insertion |
| Horizontal rules | Document structure |
| Undo and redo | Editing tools |
| HTML source view | Source editing |
| Preview | Viewing mode |
| Fullscreen mode | Viewing mode |
| Save HTML | Export/save |
| Word/character count | Document statistics |
That makes it useful for far more than a basic comment box. It can support blog editors, CMS fields, internal documentation tools, knowledge-base editors, email template editors, note-taking apps, form builders, help-desk systems, admin portals, and Blazor business applications that need formatted HTML content.
Customization Is a Major Strength
RTBlazorfied and rt-native are not just a fixed toolbar dropped into a page. Developers can customize the editor through CSS variables, runtime theming, toolbar visibility, preview styling, and custom buttons.
The component exposes options for hiding or showing toolbar buttons. Developers can start with all buttons hidden and opt specific buttons back in, or keep the default toolbar and hide only the features they do not want. This is especially useful when building different editing experiences for different users. For example, an admin editor may expose the full toolbar, while a user comment editor may only allow bold, italic, links, and lists.
The editor also supports runtime methods through @ref, including getting the HTML value, getting plain text, switching read-only mode, changing CSS classes, setting preview CSS files, setting preview CSS directly, reconfiguring toolbar visibility, and managing custom toolbar buttons.
Preview Styling Helps Match Production Output
A common problem with rich text editors is that content looks one way while editing and another way when published. RTBlazorfied and rt-native address this by letting developers load CSS files or inline CSS into the preview window.
Accessibility and Keyboard Support
RTBlazorfied and rt-native include accessibility features. The underlying rt-native web component is built with WCAG 2.1 AA compliance in mind. It includes ARIA support for the editor region, read-only state, toolbar, status bar, dialogs, and HTML source textarea.
The editor also includes extensive keyboard shortcuts for formatting, alignment, editing, lists, links, images, tables, code blocks, preview, HTML source view, fullscreen, and saving HTML. That makes it feel more like a serious editor instead of a basic web form control.
Popular and Still Growing
RTBlazorfied and rt-native have already reached a meaningful level of adoption. NuGet currently lists 60.8K total downloads for the package and rt-native.js has gained thousands of NPM downloads since its NPM release about a month ago. Together, those numbers show that the editor is not just a small experiment; it is gaining real developer usage across both the Blazor and JavaScript ecosystems.
