In Roblox, “Here” is the local chat for your current server, while “Global” is the cross-server chat that reaches players in the same experience. Roblox has rolled out a built-in toggle between those two chat modes, so the exact switch depends on whether you’re just a player or the game owner/developer.

For players

  • Open the chat box in the game.
  • Look for a tab or switch labeled Here and Global.
  • Select Global to chat across servers in that experience.

For game owners

  • If you’re testing your own experience, the global chat option is controlled by the game’s chat settings.
  • Roblox documentation from developers indicates the feature is tied to the experience’s communication/chat configuration, and some experiences may disable it or limit it by age group.
  • If Global does not appear, the experience may not have it enabled yet or may have it restricted by the developer.

Important note

A lot of older tutorials show how to build a custom “global chat” with scripting, but Roblox now has newer built-in cross-server chat behavior in some experiences, so those older guides are not always the right answer anymore.

Global = chat with players across servers.
Here = chat only with players in your current server.
