What options for Unity multiplayer should I choose?

Question

Game development

Hi all.
Which multiplayer architecture to choose for the game will be posted in the social. networks.
Option from Unity - Unet supports 20 players for free, but it's not clear on one server or all?
I need two players to compete at the same time and everything works out as cheaply as possible.
What options to consider?

Answer 1

It's cheaper and relatively easier to use websocket communication.
Some people use foton, but in my opinion it is too expensive because you have to pay for it all the time.
