markdownpad

A focused, Notepad-inspired markdown editor for macOS. Open, edit, save markdown files. Nothing else.

Features

Open, edit, and save .md / .markdown files
Right-click anywhere in the document (or ⇧⌘P) to flip between edit and view modes
View mode renders GitHub-flavored markdown — including tables, footnotes, syntax-highlighted code, and mermaid diagrams
Images render in view mode — both relative paths (![](images/foo.png)) resolved against the open document's directory and external https://… URLs
Interactive task-list checkboxes — click them in view mode to toggle
Live reload — edits another program makes to the open file appear immediately, merged into your unsaved changes when they do not overlap, with a keep-mine / take-theirs choice when they do
Print the rendered document (⌘P) — ink-friendly light styling, page breaks that keep code blocks, tables, and diagrams intact
Multi-window — ⌘N opens a new editor; closing with unsaved changes prompts you
Reopens the documents you had open the last time you quit
Light, Dark, and System appearance, plus 5 unified theme packs (Plain, Forest, Midnight, Solar Flare, Cherry) that style the app, code highlighting, and mermaid diagrams together — ⌘T cycles
Native macOS chrome with traffic lights, File menu, Open Recent, file-association for .md

Live preview of all five theme packs — Plain, Forest, Midnight, Solar Flare, Cherry — each in light and dark modes.
