IzPack is a one-stop solution for packaging, distributing and deploying applications. IzPack is opensource, released under the liberal Apache Software License 2.0.
It is fully cross-platform and generates a single installer. As such, it is an alternative to native solutions such as platform-specific installers and package managers.
IzPack-generated installers only require a Java virtual machine to run.
Many companies and projects have been using IzPack over the years, including Sun Microsystems, JBoss/RedHat, the Scala language project, some ObjectWeb/OW2 projects, XWiki and many more.
