Manus Sandbox is a dedicated cloud computing environment that allows AI models to perform tasks on behalf of users. Each Sandbox operates as a fully isolated virtual machine, meaning tasks can run in parallel without interference. Users benefit from a complete set of tools within the Sandbox, including networking capabilities, a file system, and various software tools. This setup enables the AI to write code, build websites, and create mobile applications, all while running 24/7 without using local resources. The Sandbox has a defined lifecycle for resource management. It creates a new instance when needed, goes to sleep during inactivity, and can be recycled after a certain period—7 days for free users and 21 for Pro users. When recycled, important files like uploaded attachments and project artifacts are automatically restored, but temporary files are not. Security is a priority, following a Zero Trust model. Users have full control within their Sandboxes, but any operations remain contained, ensuring the overall Manus service remains unaffected. Privacy measures are in place to protect sensitive data. The distinction between sharing and collaboration is crucial. When sharing, only task conversation and output artifacts are visible to recipients, leaving the Sandbox contents hidden. However, collaborators can access and modify files within the Sandbox. Users are advised to check for sensitive information before adding collaborators and to create new tasks if necessary to limit exposure. Overall, Manus Sandbox integrates a robust computing environment with strong security and privacy protocols, empowering users to leverage AI for practical tasks.
