Sandbox mode is a feature in software applications, especially in video games and development environments, that allows users to explore and interact freely without restrictions. In this mode, players can experiment with different tools, settings, or game mechanics without the pressure of completing objectives or facing penalties. This encourages creativity and exploration. In the context of video games, sandbox mode often provides an open world where players can build, modify, and create their own experiences. Similarly, in software development, sandbox mode allows developers to test code in a safe environment, ensuring that changes do not affect the main application or system.
