Project history

The GitHub repository was created on 2026-01-31. Public launch material posted on 2026-02-02 framed nono as a response to local AI coding agents running with the user's full filesystem and network permissions.

The core design uses kernel primitives instead of a container runtime: Landlock on Linux and Seatbelt on macOS. The project also exposes SDK directions beyond the CLI, with docs for a Rust core library plus Go, TypeScript, and Python integration paths.

Release activity accelerated quickly in 2026. GitHub release metadata shows v0.66.0 published on 2026-06-29, and Homebrew packaged the same stable version in its 2026-07-01 formula data.

Adoption history

nono is young, but it had already become unusually visible for a 2026 security CLI: the GitHub repository had thousands of stars by 2026-07-01, Homebrew reported thousands of installs across 90 and 365 day windows in its 2026-07-01 formula data, and discussion/examples focus on sandboxing AI coding agents rather than generic process confinement.

Because the project is close to the AI-agent security wave, adoption should be treated as early-stage and volatile. The reliable source-backed claim is that it had rapid package-manager and GitHub traction by mid-2026, not that it had become a mature standard.

How it is used

Typical CLI usage wraps an agent or command with explicit filesystem and network capabilities: examples include `nono run --allow . -- claude`, separate `--allow` and `--write` paths, `--net-block`, and `--dry-run`. The docs and launch post also describe default protection for sensitive paths such as SSH keys, AWS credentials, and shell configs.

Package users reach for it when they want OS-enforced guardrails around an AI agent, build step, test run, or data-processing command without building a container image. The important operational model is that child processes inherit restrictions once the sandbox is applied.

Why package nerds care

nono is notable because it packages a security boundary as a normal CLI wrapper for developer workstations. For package nerds, the interesting part is not only the Rust binary but the distribution of OS-specific confinement behavior through one command: Landlock-backed Linux behavior, Seatbelt-backed macOS behavior, and formula variants that differ by platform dependencies.
