VibeBox: Ultrafast CLI for fast, sandboxed development and LLM agents

VibeBox is a lightweight, ultra-fast sandbox that lets AI agents run commands, modify files, and execute code freely without permission prompts securely. It is completely isolated using Apple's Virtualization Framework, so your actual system stays safe with minimal memory and disk usage.

What the image shows: one command to enter an isolated environment + session management (supports multiple projects / multiple instances)

You can freely run commands, modify files, and execute code—without constant permission prompts. And because it uses Apple’s Virtualization Framework for full isolation, your real system stays safe, while using significantly fewer resources than traditional Docker or devcontainers.

Features

  • Warm start is usually under 6 seconds (measured on an M3), so jumping in and out feels instant.
  • One command: vibebox — enter the sandbox directly from your project directory.
  • Config lives in vibebox.toml: adjust CPU / RAM / disk / mounts easily.
  • Clean, minimal session management with support for multiple projects and instances.
