Multitui

Multitui is a macOS app factory designed to convert Terminal User Interface (TUI) programs into dedicated, native macOS applications. It allows users to wrap command-line tools like Claude Code, lazygit, htop, and vim into individual .app bundles with their own dock icons and window management. A standout feature is its integrated sandboxing, which leverages macOS's built-in sandbox-exec to provide fine-grained filesystem protection. This ensures that CLI tools or AI agents can run with restricted permissions, preventing them from deleting or modifying sensitive data unless explicitly allowed. Each app maintains its own shell history, snippets, and visual themes, providing a first-class macOS experience for power users.
