In this paper, we proposed a novel, free, and open-source server-side executor for Roblox, called FreeRobo. Our executor provides a lightweight, secure, and high-performance solution for users, outperforming existing solutions in terms of latency and throughput. We believe that FreeRobo will become a valuable tool for Roblox developers and players, enhancing the overall gaming experience.
