I’m testing TeleportService but unfortunately, Studio doesn’t allow testing this.
So, I have to publish the game and test it via Roblox Player.
However, to test TeleportService with multiple users, the game cannot be private.
But I don’t want to leave the game public in the middle of development, for the obvious reasons of not having unwanted users getting into it.
How to test a private game with multiple users?
If you create the game as part of a group rather than individually, this is easy to do. Just restrict access to the group and make the group private. For individually-created games under your account, I don’t think there’s an easy way to do this other than creating a script to kick unallowed players. You can also pair this up with a VIP server which you only allow people you want.
Sorry for butting in, but yes, creating a group only cost 100 Robux 
Hope this helps
Hello @rogeriodec_games
Before Spending you’re Robux, you Can Always Use Adonis Moderation
With the command :Createserver you can create a Custom Private server without paying nothing, and you can test it with all the players you want, For Access to it just use the command :place user (NameServer)
Correct me if I’m wrong but inside Studio in the Game Settings tab, there are Permissions. In that area you can add someone and click a drop down list by their name and instead of edit you can let them play only.
In OP you can see I’m referring to TeleportService.
