Multitui
Turn your terminal tools into safe, sandboxed macOS apps, because giving AI agents free rein is like inviting a toddler to reorganize your filing cabinet.
Multitui transforms command-line tools and TUIs into secure, first-class macOS applications. It uses macOS's built-in sandbox-exec to protect your filesystem from untrusted code, allowing you to run AI coding assistants and other tools safely without containers or VMs. It provides fine-grained access control, native app integration, and a customizable workflow.

How to use Multitui?
Download Multitui for macOS, then use it to wrap any terminal-based program into a dedicated app. Configure sandboxing rules to restrict file access, protecting your system while letting tools like Claude Code or lazygit run. Launch these apps from Finder, the Dock, or with global shortcuts. Use them for specific projects with isolated histories and visual styles to maintain context and safety.
Multitui 's Core Features
Sandboxes any TUI using macOS's sandbox-exec for fine-grained filesystem protection, defaulting to deny writes/deletes with targeted allow rules for specific paths.
Creates dedicated .app bundles for each tool with full macOS integration, including Dock icons, Spotlight search, and native window management.
Offers deep Finder integration with toolbar buttons, context menus, and file handler registration for opening documents directly.
Maintains isolated shell command history and snippets for each app, keeping your main terminal environment clean and organized.
Allows extensive per-app customization including themes, colors, and custom icons for visual contextual awareness (e.g., red for production).
Provides SSH integration to run remote TUIs securely and works seamlessly with system tools like Little Snitch for network control.
Features a live deny log that shows blocked actions, enabling users to quickly add allow rules and refine their security policies.
Multitui 's Use Cases
Developers running AI coding assistants like Claude Code safely, preventing them from accidentally modifying or deleting critical project files outside a designated folder.
System administrators monitoring resources with tools like htop or network connections with snitch, each in a dedicated, always-on-top window launched via keyboard shortcut.
Data analysts working with SQLite or JSON files using harlequin or jqp, opening files directly from Finder with a right-click on the data file.
DevOps engineers managing Docker containers with lazydocker in an isolated app, using a custom theme to visually distinguish it from other terminal sessions.
Writers or researchers using text editors like nano or treemd for specific projects, with each app maintaining its own recent documents list for quick access.
Power users creating menubar widgets for system info (like IP address or weather) that auto-reload, keeping vital data always visible without cluttering the terminal.
