azclient -- Customizable VPN Client

Build Status

This is a customizable VPN client, meant to be simple and sleek. It was originally built for AzireVPN, but has been designed from the beginning for customization in other contexts. Without modifying anything, it will currently build with the AzireVPN branding.

Linux Dependencies

  • OpenVPN
  • Qt 5 (specifically: QtCore, QtWidgets, QtGui, QtNetwork, QtSvg)
  • PolicyKit
  • Recent C++11 compiler

On Ubuntu, these may be installed via:

$ sudo apt install build-essential libqt5*5-dev qt*5-dev qttools5-dev-tools policykit-1 openvpn qtchooser

Building and Installing

After acquiring the dependencies, you may build and install the application.

$ qtchooser -run-tool=qmake -qt=5  # Alternatively, just `qmake` might work
$ make
$ sudo make install

The make install target takes DESTDIR and PREFIX as standard environment variables.

Other Platforms

This also works quite well on macOS and Windows. See the READMEs in dist/mac and dist/win for an overview of the build systems and installer generation.


This project may be discussed in #azclient on Freenode.


This is a customizable VPN client. To change the branding, adjust the following files:

  • customization.h contains the various strings used to name the application.
  • resources/ contains all of the images and icons, as well as CSS theming info and CA pre-loads.
  • resources/ca.crt may be optionally added, which will lock the program to only using the CAs specified.
  • dist/ contains installer scripts and code signing commands. You will likely need to change several strings in here.
