HyperMD is a WYSIWYG Markdown editor for browsers built as a set of CodeMirror add-ons, modes, themes, and keymaps. It renders Markdown formatting live while writing, blurring the line between editing and previewing.
Use cases
- embed a wysiwyg markdown editor in a web app
- edit markdown with live preview while typing
- support latex math and mermaid diagrams in a markdown editor
- paste html and convert it to markdown
- upload images via clipboard or drag and drop in an editor
- add clickable todo checkboxes and footnotes to markdown editing
When to choose
- you already use CodeMirror and want markdown wysiwyg on top of it
- you need a browser-based markdown editor with math, diagrams, and emoji support
- you want a modular, extensible editor with powerpack integrations like KaTeX or MathJax
When to avoid
- you need a standalone desktop markdown app rather than an embeddable browser component
- you want a block-based Notion-style editor instead of CodeMirror-based editing
- you need actively maintained software with recent releases
