S&box (pronounced Sandbox) is an upcoming game engine and platform developed by Facepunch Studios, intended to be a spiritual successor to Garry's Mod. It aims to surpass Garry's Mod rather than simply being a modern version of it. The platform is designed to allow users to create, share, and play a variety of games and experiences.
