Realtime Multiplayer Facebook Instant Game - Firebase vs Socket.io vs Colyseus for backend

[Doyban 2]

Planning to develop 1 realtime multiplayer game, which would target Facebook Instant Games with further possibility to extend this into Cordova-wrapped Android/iOS app.

The FPS must be rather high, as half second of a delay in the could influence the final battle result.

Therefore, for the backend wondering between Firebase, Socket.io or Colyseus and looking for an opinion of someone experienced with that topic what would perform best for this scenario.

@Doyban If you don't get answers here, I suggest posting here: https://www.facebook.com/groups/instantgamedevelopers/

@Noel tried there as well and basically Firebase might give a little delay based on the answers there (not too many though). Wanted to try different source to compare opinions, tried also Stack Overflow, but completely nothing there.

In terms of solution it seems to be Colyseus will be the preferred choice.

@Doyban I see, sorry I wasn't more helpful, not very knowledgeable on that specific topic. Thanks for sharing!
