Is there Home assistant native hardware support?

Hey,
although I was reading through the docs a while, I am not sure if I got it right:
Is Home Assistant “just” managing the several vendor bases, which are triggering their connected device or is it possible to use the device w/o the base device?

E.g. Phillips Hue, do I still need the Hue Bridge or is it possible to connect the lamps directly?
Does it mean, if I would install " Zigbee2MQTT" to Home Assistant it would work like this?

Yes if you have another way of communicating Zigbee. Like conbee stick or similar.

Cool, now it becomes really interesting
