Download the native Markdown app for macOS.

Install with the method you already use

Direct download: open the DMG, move Downright to Applications, and launch it once to finish system integration.

brew tap ezzy1630/downright && brew trust --cask ezzy1630/downright/downright && brew install --cask downright

Homebrew cask: the public tap installs the same rolling main-channel DMG as the direct download and command-line options. The tap-qualified command is available now; the tap-free official Cask command remains a separate Homebrew review.

curl -fsSL https://downright.cc/install | bash

Shell installer: the first-party installer verifies the published checksum and app signature, installs into Applications, registers Quick Look and Finder integration, and links the down and md commands when possible.

npx --yes downright-installer

npm launcher: the published downright-installer requires Node.js 18 or newer and invokes the same first-party macOS installer.

All four acquisition paths converge on the same Downright.dmg. After installation, the signed production app checks the Sparkle appcast; each verified push to the app's main branch publishes the next update.
