FloralMD is a Markdown editor built for Mac computers. Its main idea is simple: you should be able to open a single Markdown file from anywhere on your computer and start reading or editing it right away, without first creating a folder or a special workspace for it. Tools like Obsidian ask you to set up a vault before you can work, and FloralMD skips that step entirely. When you open a file, FloralMD renders the Markdown as you type, similar to how Typora or Obsidian look, so you see formatted text instead of raw symbols. You can keep several files from different folders open together as tabs in one window, and a sidebar helps you find nearby or already open documents. There is also an outline view that summarizes the current document using its headings, lists, and code blocks, plus markers showing where the file has changed compared to its last saved Git version. A few extra features stand out. It integrates with Finder's Quick Look, so pressing the space bar on a Markdown file shows a proper rendered preview instead of plain text. It also supports floating notes, meaning a document window can stay on top of other apps with a see-through background, useful for jotting quick notes while working elsewhere. FloralMD is built using Swift, AppKit, and TextKit 2, meaning it is a native Mac application rather than one built with Electron, and it works offline by default while blocking unsafe external content unless you allow it. Installation is done by downloading a DMG file from the project's GitHub releases page and dragging the app into the Applications folder. Because the app is not yet signed with an Apple Developer ID or notarized, macOS may warn about an unverified developer, and the README explains how to allow it manually through system settings. Building from source requires macOS 14 or later and Xcode, and relies on a handful of external libraries for Markdown parsing, math rendering, and update checking.
