MDEZ++ (mdez) is an open-source, lightweight, cross-platform C++20 and Qt GUI Markdown editor. Instead of a WYSIWYG editor, MDEZ++ renders a real-time live preview of your text in a split-screen pane using a fast, native, and minimal GUI.

Write raw Markdown on the left to preview rendered text on the right.
