MDedit is a free, MIT-licensed Markdown editor for Linux, macOS, Windows, and the web.
What MDedit is
MDedit is a free, MIT-licensed Markdown editor for Linux, macOS, Windows, and the web. Built with Tauri, it combines source editing, live preview, native local-file handling, and offline exports without requiring an account, telemetry, document uploads, or server-side rendering. Its tabbed workspace provides synchronized Edit, Split, and Preview modes, with independent state for each open document. Markdown support includes GitHub-flavored syntax, task lists, tables, footnotes, callouts, syntax highlighting, Mermaid diagrams, and KaTeX math. Per-document find and replace supports match-case, whole-word, and regular-expression modes. Documents can be exported as HTML, PNG, PDF, CSV, or SVG. Desktop versions keep local recovery snapshots and restore tabs and workspace state after an unexpected shutdown. Browser sessions cannot resolve Markdown files on disk, desktop-imported attachments are limited to 20 MiB, and listed desktop builds are unsigned. Cloud sync is not supported.
