Everything you need

Block Architecture

Independent editable blocks with explicit serialization, validation, lifecycle, and document renderer contracts.

21 Block Plugins

Paragraph, media, carousels, tables, layouts, polls, people, attachments, previews, and more — each individually importable.

Inline Tools

Twelve default tools for formatting, links, code, color, font size, alignment, scripts, case, and cleanup.

Drag & Drop

Reorder blocks with keyboard-accessible controls, drag handles, selection, and configurable animation.

Undo / Redo

One completed action is one ordered history step across formatting, widgets, paste, split/merge, and block commands.

Versioned JSON

A stable document contract with deterministic migrations, validation modes, and plugin-owned data.

i18n

Built-in English and Russian dictionaries with scoped localization contracts for extensions.

Themes

Light and dark editor themes built on CSS custom properties and runtime-selectable appearance.

Framework Agnostic

Browser-native ESM that integrates with any application stack without coupling the editor to a UI framework.
