Build Status


Nally, every platform, every machine.


Qelly (pronounced as the English name "Kelly") is a Qt port of Nally, the open-source Telnet/SSH client for Mac OS X. Qt is chosen to be the underlying framework of this application bacause it enables us to build a GUI-based application with a native-looking interface for every operating system with minimal effort. The project is currently only a Qt version of Nally (hence the name), but more features from other Telnet/SSH clients are also planned.


Qelly is published under the terms of GNU Public License version 3 (GPL v3) as defined by the Free Software Foundation (FSF). A copy of the license should have been included with this file. You may also find the details of GPL v3 at:

Special Notices on SSH Feature

The SSH connection is driven by external executables. In Unix-like systems, the OpenSSH client, which is built-in in most cases, is used. Under Windows, Plink (PuTTY Link command-line interface) is used.

You can get Plink at the PuTTY project download page:

Or, if you don't know which one to download, you can use this direct link:

The SSH client path can be put anywhere you wish to, as long as you specify its location correctly in Qelly's Preferences.


Qelly depends on Qt, LibQxt, and optionally QJson. Currently both Qt 4.8 and 5+ are supported. You can find more information regarding installation on Qt, libqxt and QJson's respective project pages:

JSON Backends

LibQxt's JSON processor, QxtJSON, has a serious bug in 0.6.1, which is subsequently fixed. APT, unfortunately, only has the old, buggy version to this date. The alternative implementation based on QJson is provided to address this specific problem.

If you intend to build Qelly using the QJson-based implementation, run qmake with an additional argument DEFINE+=QJSON, i.e.:


For those using newer versions of LibQxt and doesn't need QJson, simply run qmake without the DEFINE+=QJSON argument.

APT-based Installation

If you use an APT-based package manager, the content of .travis.yml provides a minimalistic build environment setup. It is currently based on Qt 4.8.1, LibQxt 0.6.1, and (optionally) QJson 0.7.1.

Other Package Managers

Alternatively, if your package manager of choice (such as YUM, Homebrew, etc.) provides Qt, LibQxt and (optionally) QJson, you can install both them manually.

LibQxt Setup Without Package Managers

If you wish to build LibQxt manually, you will need to choose an appropriate version based on the version of Qt tha you use. At the time of writing (2013-09-25), the latest stable LibQxt release (0.6.2) supports only Qt 4. Therefore, if you wish to build Qelly against Qt 5, you will need to use Git or Mercurial to clone the tip version, and build LibQxt from that.
