Even though OpenPetra is not ready for production use yet, you can already download a Preview version. We will regularly release the latest Preview to show the progress of the project and to get feedback from you!
A Basic Tutorial can be found here.
At the moment, only a standalone version of OpenPetra.org for Windows is available for download.
It comes with a base database with some demo data. To login, use the user demo and the password demo.
Below are the most recent Petra releases with the download link and some notes about each release.
