I've heard good things about XCP-ng as well and tried it out at home and proxmox seems much easier to use out of the box. Not saying XCP-ng is bad just that it wasn't as intuitive to me as proxmox was when we were moving away from vmware

And there's also Triton[0] and vanilla SmartOS[1] it's based on

Ex XCP-ng user here. The web management portal requires Xen Orchestra and needs to be installed as a seperate VM which can be irritating, with a seperate paid license. Proxmox has a web GUI natively on install which is super convenient and pretty much free for 90% of use cases.

Xen Orchestra appears to be open source:

* https://docs.xen-orchestra.com/installation#from-the-sources

See also perhaps:

Yup, I have two xen orchestras running on different vm clusters in different DCs managing about 8 pools (some on all the time, some in vehicles which are sometimes on, sometimes off), all open source, works well enough.

I don't change the pools enough to make it worth automating the management.

This channel (https://www.youtube.com/@LAWRENCESYSTEMS) has a lot of xcp-ng content, and also has several proxmox vs xcp-ng discussions over the years (eg https://www.youtube.com/watch?v=et54DxAC2uM)
