Sandvault: Run AI agents isolated in a sandboxed macOS user account (github.com)

SandVault has introduced a new tool that allows developers to run AI agents like Claude Code, OpenAI Codex, and Google Gemini in a secure, isolated macOS user account. This "sandvault-$USER" environment limits system access for these AI models, offering a lightweight alternative to traditional virtual machines. With features like fast context switching, passwordless account switching, and straightforward installation via Homebrew or Git, SandVault streamlines the process of experimenting with untrusted code while maintaining robust security. This solution is significant for the AI/ML community as it facilitates safe experimentation and deployment of powerful AI tools without the overhead of virtualization. Utilizing macOS's Unix-based architecture, SandVault ensures that the isolated user cannot access sensitive directories, thus providing a clean separation between trusted and untrusted environments. Developers can easily run and test various AI capabilities while locking down access to crucial system files, significantly enhancing security during the development cycle. SandVault demonstrates the potential for utilizing native operating system features to bolster both usability and safety in AI development environments.
