I've liked Input Director https://www.inputdirector.com/ a lot more than Mouse Without Borders on Windows systems. If you need multi-platform Input Leap (previously Barrier) is the best alternative I've tried https://github.com/input-leap/input-leap.
Input Leap has wayland support as well. https://github.com/input-leap/input-leap
It's not clear from the page, but there's an issue somewhere that points out barrier has been abandoned for a fork called input-leap.
https://github.com/input-leap/input-leap
Also recently learned about waynergy as a upcoming wayland client. Haven't used either yet as barrier still handles my setup.
Barrier has been abandoned, the currently supported fork is now called input-leap: https://github.com/input-leap/input-leap
Can someone comment on Barrier vs input-leap? (https://github.com/input-leap/input-leap?)
It looks like input-leap has drag-drop in the works, but apart from that I have no clue which one is the blessed one right now.
Barrier has been forked to https://github.com/input-leap/input-leap which has a hundred more commits by the same devs.
The name is still barrier though, has anyone more info about this fork?
