🧱

Block-first

Paragraphs, headings, lists, quotes, code, tables, images, callouts, and toggles — every block is a typed node in a predictable document tree.

📦

JSON-first, never opaque HTML

Documents are portable, versioned JSON (schemaVersion 1.0.0). Lossless Markdown and HTML interchange is built in — your content is never locked inside the DOM.

⚡

Transaction-driven

Every edit flows through a single write path with all-or-nothing commit and mechanical undo. The DOM is only a view of the document state.

🪶

Zero dependencies

No runtime dependencies. A single ESM bundle, a UMD build, types, and one CSS file — drop it anywhere from bundlers to plain script tags.

♿

Accessible

Keyboard-complete editing, ARIA menus and live regions, RTL support, reduced-motion handling, and a WCAG 2.2 AA target.

🔒

Secure by default

Sanitized paste and imports, a URL allowlist, prototype-pollution stripping, depth caps, and DOM building without eval or innerHTML of untrusted content.
