I was wondering if the use of the essential mod could be allowed for co-op speedruns, only for the feature of letting another person join your singleplayer world. I have used this this mod multiple times, (not for speedrunning purposes) and it has worked wonderfully. The reason i’m asking is because it is nearly impossible to get a server working that both my friend and I can join. We have tried multiple different other options and this is the only one that consistently works for us. I understand that the mod has multiple other features but I believe most of them can be disabled or at least do not affect the game itself. Thank you for your consideration. Thanks.

Use ngrok instead there is no reason to allow the mod because ngrok exists. Sometimes it might not work so just try again and restart ngrok if you come across any problems.

Is the port force mod allowed for speedruns?

yes
