Milkdown
What it is
Milkdown is a free, open-source framework for building WYSIWYG Markdown editors on the web. Its plugin architecture lets developers select or add syntax, themes, interface elements, and other editor capabilities. The framework has a headless design with no bundled CSS, so projects can define their own appearance. Milkdown supports real-time collaborative editing through Y.js and documents slash menus, tooltips, LaTeX equations, tables, Markdown clipboard handling, and emoji shortcuts. It is built on ProseMirror and Remark, with examples for custom interfaces in React and Vue. The @milkdown/kit package re-exports core functionality, presets, plugins, and components for project use. Structured content, table editing, and image handling are supported; image tools include uploading, resizing, captions, inline embedding, and uploader support. Milkdown is available under the MIT license and is described as free to use, with no paid plan or usage limits stated.
