Quick Scoop

In Roblox Studio, you usually can’t make someone a true “co-owner” of a personal experience. Roblox generally supports one owner for a game, and the practical workaround is to put the experience in a group and give the other person a higher group role with edit/configure permissions.

What to do

  1. Create or use a Roblox group for the game.
  2. Move the experience to that group from Studio or the experience settings.
  3. Add the person to the group and assign them a custom role like “Co-Owner.”
  4. Give that role the permissions to edit the experience, manage places, and configure group assets.

Important detail

If you’re trying to change the actual owner of the experience, Roblox’s newer group/ownership workflow is the closest supported path, and forum guidance points to ownership transfer or group-based collaboration rather than multiple owners on one personal game.

Simple version

If you want two people to run a Roblox game together, make it a group- owned game and give the second person a powerful group rank. That works much better than trying to force a second owner into a personal place.

TL;DR

  • Personal Roblox experiences do not really have a shared co-owner system.
  • Use a group-owned experience instead.
  • Make a custom Co-Owner role and grant the needed permissions.
