I want to build a little device that connects two computers together via usb, and send keystrokes from one to the other.

(I would use it to use a laptop keyboard on a headless computers).

I am looking for an easy solution, it does not have to be the cheapest.

ChatGPT points me to Arduino, but as far as I can see, there's no arduino with 2 usb ports. It also points me to Raspery pi zero, but that's a computer, not a microcontroller, so not sure if it's suitable.

If anyone with experience can give me some pointers, it would be greatly appreciated!

Raspberry Pi definitely works! I have a project you can take a look at; you'll have to modify it slightly since you want a keyboard rather than a joystick, but they're both HID so the majority of it should work pretty much out of the box: https://github.com/saulrh/composite-joystick.
