How to make an easy 2d local 2-player multiplayer game

Hi guys,

I’m working in a team planning to make a simple multiplayer board game on webpage. I’m investigating network solutions to let two players play our game on different devices.

I’ve found solutions like Photon. These solutions requires a separate server, which seem to overkill for a 2-player game. I’m wondering if there is any easy way to utilize local networks to let 2 players to interact on different devices?

Many thanks
