OpenWebStart is available for macOS, Windows and Linux. The recommended minimum system requirements of OpenWebStart itself are:

  • 2 GHz dual core processor
  • 1 GB RAM (system memory)
  • 200 MB of hard-drive space (for the OpenWebStart core installation)

In addition to that, memory and hard-drive space consumption are mainly influenced by the number of JVMs downloaded and the JNLP applications installed and cached on your system.

Latest stable release: 1.9.1

(*) Other OS versions and configurations may work but have not been tested.
