To add Roblox to your bar in Roblox Studio, the usual meaning is to place a custom button or UI element in the top bar area, and the simplest modern way is to use a top-bar UI module like TopbarPlus or to build your own ScreenGui and position it to match the top bar. Roblox developer discussions note that you can’t directly place a normal button into the core top bar, but you can mimic it with your own UI or use a top-bar button framework.

Fast setup

  1. Open Roblox Studio.
  2. Add a ScreenGui to StarterGui.
  3. Create a Frame or TextButton for your custom bar item.
  4. Position it near the top-right or top-left to match the Roblox bar.
  5. If needed, set IgnoreGuiInset to true so your UI can sit flush with the top edge.

Best option for top-bar buttons

If you want an actual top-bar style button, a purpose-built module such as TopbarPlus is the common approach, because it is designed for custom icons, labels, and button behavior in the top bar area. Community examples also show custom hotbar scripts that hide the default toolbar and replace it with a custom GUI if you mean the in-game item bar at the bottom of the screen.

If you meant the hotbar

If by “bar” you mean the tool hotbar , the process is different: you usually put Tools in StarterPack, and Roblox automatically shows them in the default bar, or you create a custom hotbar GUI and script tool selection yourself. A tutorial example shows adding a ScreenGui, building slot buttons, then using a LocalScript to handle equip and unequip logic.

Simple guidance

  • For a top bar button , use a top-bar UI module or custom GUI placement.
  • For a tool hotbar , use StarterPack or a custom hotbar script.
  • For UI alignment at the top, consider IgnoreGuiInset.

TL;DR: If you mean the Roblox top bar , you can’t directly drop a normal button into it; use a top-bar UI module or mimic it with your own GUI. If you mean the tool bar/hotbar , you can either use Tools in StarterPack or build a custom hotbar script.
