capsicain VS keyd

If you want to have layers without buying a QMK keyboard there's some software solutions like capsicain (most powerful, harder to configure, has limitations when working with wireless keyboards), Microsoft Powertoys keyboard manager (easy to configure, very limited with what you can do) that allow the same kind of functionally.

Capsicain is another one: https://github.com/cajhin/capsicain Gotta try 'em all!

The mod has better split, almost orthogonal, two levels of thumb cluster, I use capsicain for this mod, find the config on this link

This is great. Is it possible to somehow use it with keyd, as I don't use autohotkey?

There's some customizations I did with keyd that could be useful for others. See here

On Linux, I use keyd[1] and while I understand that keyd itelf could never run on the Mac, I'd love something that could take my keyd conf and make it work (even approximately) on the Mac.

I had the same problem as you, download keyd then follow their instructions to enable the background service.

Using Sway means no Xmodmap stuff obviously, so I had previously used caps2esc: https://github.com/weirane/caps2esc and then switched to keyd: https://github.com/rvaiya/keyd

There are a lot of daemons for keyboard remapping. I use kmonad, but i was going to try keyd and kanata. Both kmonad and keyd are on the package repository. kanata is not. Kanata with the tcp server could be useful for non global configuration.
