nono is an innovative open-source sandbox designed to provide a fortified environment for AI coding agents and LLM functions through kernel enforcement. Unlike conventional policy-based guardrails that simply supervise and filter actions, nono effectively utilizes operating system security features—specifically Landlock on Linux and Seatbelt on macOS—to render any unauthorized operations impossible at the syscall level. With a single command, users can encapsulate any AI agent, such as Claude Code, OpenCode, OpenClaw, or any command-line interface process, ensuring a streamlined experience. The system automatically implements a default-deny policy for filesystem access, limits dangerous commands (like rm, dd, chmod, and sudo), isolates sensitive credentials and API keys, and extends these restrictions to all child processes, effectively preventing any possibility of evasion once the constraints are established. Featuring built-in profiles for quick deployment, it allows for secure injection of secrets from the system keystore, including automatic zeroization upon exit for added safety. Future upgrades are on the horizon, including audit logging, atomic rollbacks, and Sigstore-attested policy signing, which will enhance tracking and security capabilities. Operating under the Apache 2.0 license, nono is developed by the same creator behind Sigstore, underscoring its trustworthiness and effectiveness in securing AI workloads while continually evolving to meet future security needs. Moreover, its commitment to open-source principles ensures that it remains adaptable and transparent for users seeking robust AI development solutions.
