Pricefx Studio runs on any Linux/Windows/Mac OS with Java 8 and higher, Java 11 is recommended.
The Pricefx Studio plugin is currently supported for IntelliJ IDEA version 2019.2 and higher.
Important note
The current version of the plugin may not work perfectly with any of the future IDEA versions. So unless you are a geek or you want to help Studio development team adopt the plugin to the new version quicker, you should wait with the IDEA upgrade.
