Multitui

Sandbox claude code, codex, gemini, or any TUI on macOS without changing your workflow.

Multitui protects your filesystem when running untrusted code by creating highly-customizable individual macOS terminal apps for your favorite TUI and command line programs.

Why Multitui?

• Sandbox: Your filesystem, your rules. Multitui uses the macOS built-in sandbox-exec to give you total control over what files the TUI can see, read, and edit. Run with --dangerously-skip-permissions without worrying about your filesystem outside of your project folder.
• Keep your dev environment: You don't need to launch a container or VM.
• Native apps: Fast and efficient, native Swift app. Native integrations, like Finder toolbar button, recent documents, customizable toolbar, global shortcut, and dock icon.
• Built for power users: Extensive options to build apps for your favorite tools and your unique workflow.
