DownloadGet QRZero
Every version is on the GitHub releases page. Open the newest one and pick the file for your computer from its Assets list.
| Platform | File | Notes |
|---|---|---|
| Windows | QRZero_<version>_x64-setup.exe | The normal installer. Start here. |
| Windows | QRZero_<version>_portable.exe | Nothing to install: copy it anywhere and run it. |
| Windows | .msi | The same app as an MSI, for managed installs. |
| macOS | QRZero_<version>_aarch64.dmg | Apple Silicon (M1 or newer), macOS 11+. Read the first-launch steps. |
| Linux | .deb / .rpm / .AppImage | Debian and Ubuntu, Fedora and openSUSE, or any distribution (make the AppImage executable). |
| Linux, headless | QRZero-server_<version>_linux-x86_64.tar.gz | No window: run it on a shack PC and use it from a browser. |
| Windows, browser mode | QRZero-server_<version>_windows-x86_64.exe | The same server for Windows. Close the desktop app first. |
Opening QRZero on a Mac the first time
The Mac version is not signed with an Apple Developer account, so macOS blocks it on first launch. The file is fine.
Drag QRZero into Applications, then do one of these:
- Control-click (right-click) QRZero, choose Open, and click Open in the warning.
- Or try to open it once, then go to System Settings → Privacy & Security, scroll down and click Open Anyway.
- Or run this in Terminal:
xattr -dr com.apple.quarantine /Applications/QRZero.appIf macOS says QRZero is damaged and can't be opened, use the Terminal command. It only needs to be done once per downloaded version.
Where your log lives
| Windows | %APPDATA%\QRZero\qrzero.db |
| macOS | ~/Library/Application Support/QRZero/qrzero.db |
| Linux | ~/.local/share/QRZero/qrzero.db |
QRZero checks GitHub once a day for a newer release and shows a link in the top bar. It never downloads or installs anything for you, and the check can be turned off in Settings → General.
