Ready packages
These are packages ready for use and are the recommended download for normal users. They are pre-packaged with motor thrust curves from thrustcurve.org.
OpenRocket requires Java version 6 or later. The Sun Java Runtime is recommended.
Development release
The development release contains the latest and greatest features, but may contain more bugs than the stable version. Currently the development version is the recommended download.
Stable release
Occasionally during OpenRocket development focus will shift from feature development towards getting all open bugs fix and to produce a stable release. No updates are made to the stable branch except for possible bug fixes, so the stable release has less features than the development release.
The current stable release is OpenRocket-1.0.0.jar
Running OpenRocket
OpenRocket can be started in most graphical environments (including Windows) by double-clicking the package icon. No installation is required.
From the command line OpenRocket can be started by java -jar OpenRocket-1.1.0.jar
Source code and older versions
Source packages and older versions of OpenRocket are available in the SourceForge repository.
Alternatively, the most recent development version can be obtained from the SVN repository. It can be retrieved simply using the command
