Jalopy will run on any Pentium-class machine with a minimum of 256 MB RAM. You may succeed with less, but it’s not recommended for a good user experience. Depending on your options, you need between 10-20 MB free disk space for the installation files. During runtime, additional space is required for settings, caches and backup, typically between 5-50 MB, but this again depends on your project size and setup.

The supported operating systems are: Linux, Mac OS X (x86 only), Solaris, Unix, Windows XP or later. Jalopy should run on all platforms that provide a suitable Java VM.

Jalopy requires a properly configured Java JDK version 1.4 or later on your system. We recommend to use a more recent version for best performance.
