One of the FAQs after launching LinuxONE is the question: what of the currently popular applications stacks etc has been ported to Linux on z?
There is a community called "IBM LinuxONE and Linux on IBM z Systems Open Source Ecosystem" that in the forum has a list of projects ported/tested. Don't get confused by the date of the entry, look at the bottom for the latest update.
If you are missing something, feel free to ask the question in the forum.
