FalconMD

A lightweight native macOS Markdown editor. Formatting appears as you type.

Requires macOS 15 and Xcode 26.

Features

• Open, edit, and save .md / .markdown files
• Live Markdown styling (headings, emphasis, lists, quotes, code, links, images)
• Start page with New, Open, and recents
• Find / replace (⌘F)
• Raw source toggle (⌘\)
• Format menu scoped to the current window
• Paste or drop images into {filename}.assets/

Build

Open FalconMD.xcodeproj in Xcode, select the FalconMD scheme, and run.

Command line:

xcodebuild -project FalconMD.xcodeproj -scheme FalconMD \
  -destination 'platform=macOS' -derivedDataPath build/DerivedData test

The Debug app lands at:

build/DerivedData/Build/Products/Debug/FalconMD.app

You can also open Sample.md with File → Open.

GitHub Actions

Pushes to main and pull requests run tests without uploading an app artifact.

Pushing a version tag such as v0.1.0 builds a universal Release app, creates FalconMD.dmg, and publishes both the DMG and its SHA-256 checksum on the matching GitHub Release. The stable latest-download URL is:

https://github.com/cyx2007/FalconMD/releases/latest/download/FalconMD.dmg

The app inside the DMG is ad-hoc signed. Public distribution without Gatekeeper warnings still requires a Developer ID certificate and notarization.
