option but honestly I just haven't explored it yet for a multi-client setup.
I have one Unifi Controller with 70 Customers and they have each their own login and can manage it from their end. This one is not hosted on Vultr but rather in AWS but it is working well.
Moving to Vultr though very soon.
Yeah, I've worked with a single instance managing 200+ customers. Easy, especially when you can adopt a new AP before taking it on site.
