Is Zigbee automatic enabled?

This is maybe a dumb question but is Zigbee automatic enabled right away? I’m using HA core and i saw with Z-wave that you first need a separate z wave server. Is that also needed by Zigbee or is just plugin the zigbee stick in my proud C4 enough with HA core running?

It depends how your run your setup. You will need some type of Zigbee controller and ‘usually’ something like Zigbee2MQTT and an MQTT server running. If you run your setup differently you may be able to just to a Zigbee Add-on but you will still need some type of Zigbee controller. There are some Zigbee to Wifi controllers that you don’t need anything else.

Yeah I mean I know that i need to buy some usb zigbee controller but thats the only thing I need right? i just plugs the controller in the sbc and configure it with ZHA?

BOTH Zigbee and ZWave basically behave the same way

You need: A compatible controller that works with your controller software:
For Zwave that’s the ZwaveJS integration (builtin )or ZwaveJS_UI (addon/Server or otherwise) or some third party software
For Zigbee that;s ZHA (Builtin) or Zigbee2MQTT (add-on) or some other Third Party

For BOTH - if you use a USB Stick, use at least a half meter extension cord or small powered USB2 hub to keep them away from the machine - (USB3 interference is a real thing)

Once they’re installed in MOST cases HA will find the controller on its own and suggest the appropriate builtin integration - in the case of Zigbee, ZHA and for Zwave - ZwaveJS. If you dont want to use them feel free to click the ignore button on the popup and install your own addon or server.
