This project uses the following third-party libraries:

  • QOnlineTranslator - my library that provides free usage of Google, Yandex and Bing translate API for Qt5.
  • QHotkey - A global shortcut/hotkey for Desktop Qt-Applications.
  • SingleApplication - A simple single instance application for Qt.

Therefore, if you want to clone this project, you need to use the --recursive option:

git clone --recursive

or you can initialize these modules later:

git clone
git submodule init
git submodule update


Only Linux supports icon theming. Windows use Papirus icons.

FlagKit icons are used for flags.


To install a stable version, go to the releases page. The instructions below will help you install Crow Translate with the latest commits.

Automatic script

You can use the automatic script that builds Crow Translate and creates a package for your distribution:

cd dist/unix

Than you can install it as usual. The script will tell you where the package will be after the making. Currently, only Arch Linux, Debian and their derivatives are supported.

Arch Linux and derivatives

You can install crow-translate-git from AUR.

Manual building

You can build Crow Translate by using the following commands:

make clean

You will then get a binary named crow.


To help with localization you can use Transifex or translate files in data/translations with Qt Linguist directly. To add a new language, make a request on the Transifex page or copy data/translations/crow.ts to data/translations/crow_<ISO 639-1 language code>.ts, translate it and send a pull request.

You can’t perform that action at this time.
