Markmap

What Markmap is

Markmap turns Markdown into an interactive mind map, allowing plain-text outlines to become navigable visual structures. Its browser page lets users load Markdown, while the transformer extracts hierarchy and renders interactive SVG. Developers can configure branch colors, node width, initial expansion, zoom, and panning through JSON options, and extend the Markdown transformer with built-in or developer-supplied plugins. The command-line tool builds maps from Markdown files and can generate HTML with assets inlined for offline use. An autoloader can render HTML elements containing Markdown as mind maps on a web page. Documentation includes React and Vue demos and programmatic use through markmap-lib and markmap-view. The VS Code extension previews Markdown files and updates the map as the file is edited; it also works offline. Other listed integrations include Open VSX, Vim and Neovim, Emacs, MCP servers, and AI agents. Markdown headings support up to six levels, though nested lists can create deeper branches. Markmap is free and open source under the MIT license; no trial terms are listed.
