BlockNote

BlockNote — a block-based rich-text editor by TypeCellOS. A Community Component that aardvark does NOT bundle, because its source is MPL-2.0 copyleft. This page records the license verdict and links to the project.

BlockNote is a block-based rich-text editor by TypeCellOS — a Notion-style WYSIWYG editor built on ProseMirror, with a first-class Mantine theme (@blocknote/mantine). It’s a natural fit for a “Community Component” wrapper on paper.

aardvark, however, does not ship BlockNote as a built-in {% tag %}. This page exists to record why, and to point you at the project so you can integrate it yourself if its license works for your project.

Not bundled — license verdict

BlockNote’s source code is licensed under the Mozilla Public License 2.0 (MPL-2.0), a copyleft license. aardvark’s policy for Community Components is to bundle only permissively-licensed projects (MIT / Apache-2.0 / BSD / ISC) into its island bundle. Because MPL-2.0 carries file-level copyleft obligations, BlockNote is documented but not bundled. There is no {% blocknote %} tag.

License

The verdict was confirmed against two independent sources on 2026-06-19:

Source	Finding
`registry.npmjs.org/@blocknote/core`	`"license": "MPL-2.0"` (and likewise for `@blocknote/mantine`, `@blocknote/react`)
`LICENSE.txt` in the GitHub repo	“Source code in this repository is covered by the Mozilla Public License Version 2.0 (MPL-2.0), except for the XL packages.”

A few details that matter for the verdict:

The main packages are MPL-2.0. @blocknote/core, @blocknote/mantine, and @blocknote/react — the packages a wrapper would use — are all MPL-2.0.
The @blocknote/xl-* packages are GPL-3.0 (with a separate commercial license offered). These are an even stronger copyleft and are likewise excluded.
MPL-2.0 is not anti-commercial. It is OSI-approved and permits commercial use and redistribution. Its copyleft is file-level: only changes to the MPL-licensed source files themselves must be shared back. That makes it materially different from AGPL or “source-available” licenses.

aardvark’s Community Component bundling bar is intentionally narrow — permissive only — so that the island bundle (and anything built on top of it) stays free of file-level copyleft obligations. MPL-2.0, while friendly, sits on the copyleft side of that line, so BlockNote is not bundled. This is a packaging decision, not a statement that BlockNote is unsuitable — it’s an excellent editor.

Using BlockNote in your own project

Nothing stops you from adopting BlockNote directly — MPL-2.0 is perfectly usable in a commercial product. Install it into your own front-end build and follow the upstream Getting Started guide:

npm install @blocknote/core @blocknote/mantine @blocknote/react

The Mantine theme ships its own stylesheet, imported via the package’s style.css export:

import "@blocknote/core/fonts/inter.css";
import "@blocknote/mantine/style.css";

A minimal Mantine-themed editor looks like this upstream:

import { useCreateBlockNote } from "@blocknote/react";
import { BlockNoteView } from "@blocknote/mantine";

function Editor() {
  const editor = useCreateBlockNote();
  return <BlockNoteView editor={editor} />;
}

For a read-only view (the shape that would suit a static docs page), upstream exposes an editable={false} prop on BlockNoteView. See the BlockNote docs for the full API.
