I remember that at the start of all my server experience I hosted using ExaGear as well.
I really loved the product and only now learned that it has completely vanished except the android version.
It really is a shame especially because the paid licenses…
Anyhow - Upon reading about this I found this:

It is a free and open alternative to ExaGear Desktop.
I did neither test this nor do I know whether it currently works. It says only 32bit is supported though.
Also I would keep distant from any torrents of exagear you mind find, no one knows what happened to them and we have no official hashes of the last release files.
I would love to hear about your results as I can’t test it myself… All my RPis are either burnt or in use and not free for tinkering.
