Unfortunately, privacy.com is only available in the US. I had been looking for an alternative for quite some time, but recently I stumbled onto the fact that Wise (formerly TrasferWise) will give you a seemingly unlimited amount of virtual cards if you open an account with them.
As far as I can tell this isn't documented on their website, but I can definitely get new cards on demand and disable them as necessary. In fact, their website still mostly references MasterCard, however I have received a physical Visa card and the virtual cards are all Visa as well.
This isn't as sophisticated an offering as privacy.com because you can't set a fixed limit per card, but it's a lot better than nothing.
