Ah, sucks :(
I’m looking forward to see where Incus OS goes, or TrueNAS Scale. Honestly, I was very tempted to automate a procedure to take a Proxmox ZFS install and replace the Proxmox bits with Incus bits :) Incus + ZFS as an appliance would be nice. I kinda don’t want to think about the underlying OS.
Running LanguageTool locally is a bit of a pain, with some manual steps. Plus you have to fetch some data files. You can find around a few projects like this one to make it easier to run LanguageTool.
And yes, as the poster mentioned, LanguageTool keeps some code exclusive to their paid version. There’s a bit of a tension because they ask people not to extend OSS LanguageTool with their paid features.
There’s also this interesting clone, but it seems abandoned.
