Swift Explorer's Logo

This project aims at building a user-friendly tool to manage files in an OpenStack Storage system. The OpenStack Object Storage is dubbed SWIFT, hence the name Swift Explorer.

Current version (1.0.9) supports hubiC, and should work fine with any OpenStack-based system that relies on the Keystone authentication mechanism (bear in mind that no tests using Keystone have been conducted so far)1. Besides, a simulator is integrated, providing a means of playing with it, without a real back-end. Some questions? You might be interested in reading the FAQ.


OS Version Description Release Date Size Download
Mac OS X 1.0.9 App Bundle 26 Oct 2017 178 MB dmg
Mac OS X 1.0.9 Package 26 Oct 2017 76 MB pkg
Windows (x64) 1.0.9 Installer 26 Oct 2017 91 MB msi
Windows (x64) 1.0.9 Installer 26 Oct 2017 67 MB exe
All* 1.0.9 Executable Jar 26 Oct 2017 17 MB jar
* The executable jar file requires the JRE 8 or later, which can be currently downloaded for Linux (x86, x64), Mac OS X, Solaris (SPARC 64-bit, x64) and Windows (x86, x64).

The installers (Windows) and the app bundle (Mac OS) are coming with their own embedded JRE; therefore, there is no need to install any additional components (i.e., the JRE 8).

In order to use the jar file, after making sure that your machine has the Java SE 8 JRE installed (e.g., by using the command java -version), just double click on the jar file; or, alternatively, use the command:

$ java -jar SwiftExplorer-1.0.9-jar-with-dependencies.jar

If you have to deal with a gigantic number of files, the default maximum heap size of the JVM might not be sufficient. Assuming that enough RAM are available, the option -Xmx\<size\> can be used to specify a greater limit, e.g.,

$ java -Xmx4096m -jar SwiftExplorer-1.0.9-jar-with-dependencies.jar

Note: older versions can be downloaded here.

A few Details

The hubiC API

Standard OpenStack API, except for the authentication mechanism. HubiC relies on OAuth2, and has implemented a rather weird protocol (that is described in details here - basically, a first token must be obtained in order to claim a second one that is the one).


This application is written in JAVA, and extensively relies on JOSS for the core functions. The GUI is sort of a fork of Cloudie. The authentication part has been implemented using scribe-java.

  1. Since JOSS already offered the possibility to use Keystone, it should work on Swift Explorer as well.
