Multitui

Multitui transforms text-based user interface (TUI) programs and command-line tools into dedicated, native macOS applications. Key features include: • Generates individual macOS apps for any TUI program • Optional filesystem sandboxing for enhanced security • Supports folder-based and file-based command line tools • Includes terminal utilities with global shortcuts and menubar widgets • Configurable access rules for read/write operations This app factory allows you to wrap tools like claude code, lazygit, Harlequin, htop, and nano into their own secure macOS applications. It leverages macOS's sandbox-exec to provide granular control over what files and folders a TUI program can access, preventing unintended modifications or deletions. You can define specific allow/deny rules, log blocked actions, and even allow access only within designated project folders. Multitui is ideal for developers, power users, and security-conscious individuals who want to isolate untrusted code or simply make their favorite command-line tools first-class citizens on macOS. It complements existing terminal workflows by providing dedicated windows for specific tools, reducing tab clutter, and offering a more controlled operational environment without the need for containers or virtual machines.
