Best Practices for FE GUI Scripting
Open your ShopHandler LocalScript. This script lives entirely on the player's device. It will handle the visual click and pass the request to the server. roblox fe gui script

Runs in the cloud. It manages the actual game logic, saves player data, spawns items, and validates everything that happens in the game. itemName) -- (Insert inventory or tool spawning logic
Filtering Enabled (FE) was Roblox's massive security overhaul to fix this. When a game has FE enabled (which is the modern standard for all games), the server no longer trusts the client. The client sees a local version of the game, but any changes made by that client stay on that client. If a hacker tries to change their speed on their screen, the server ignores it. This is why FE is often described as the server saying, "I trust nothing you say until I verify it".
An is a script (usually a LocalScript ) that runs inside a player’s GUI, designed to work within the constraints of Filtering Enabled. However, in common Roblox vernacular—especially on forums, script marketplaces, and exploit communities—the term has two distinct meanings:
