OpenPnP is available for download for Mac, Windows and Linux. There are two versions available: Latest and Stable. Unless you are relying on an older feature set, we recommend Latest.

This is the Test branch. You should only use it if you have been asked to test a specific feature. These downloads may contain bugs and unfinished features.

While your download finishes, why not have a look at the Quick Start Guide to get the ball rolling?
