About

What is Multitui?

Multitui is a macOS application factory designed to generate individual terminal apps for TUI (Text-based User Interface) programs. It allows users to wrap any command-line tool, such as htop, vim, or btop, into a dedicated native macOS app. A key differentiator is its robust security features, including filesystem sandboxing using macOS's built-in sandbox-exec and network filtering to protect development systems from untrusted code and prevent secrets from leaking. Users can configure and preview custom terminal apps, making TUI apps behave like first-class macOS applications with features like dock icons, Spotlight integration, and window management. It also offers per-app customization for style, themes, and shortcuts, enhancing contextual awareness for power users.

Best used for

Ideal for developers who need to securely run command-line tools, create dedicated macOS apps for TUI programs, and protect their development system from untrusted code. Especially valuable for those wanting to sandbox AI agents or enhance their terminal workflow with customized, isolated applications.

FAQs

What is the difference between Multitui's Personal and Pro plans?

The Personal plan is free forever and intended for personal use, offering sandboxing, SSH integration, isolated shell history, and Finder integration. The Pro plan, free in Beta, is for professional and commercial use, including all Personal features plus priority support. A Teams plan is also planned for future work.

How does Multitui protect my files and secrets?

Multitui uses macOS's built-in sandbox-exec for fine-grained filesystem protection, defaulting to deny writes and deletes, with targeted allow rules. It also filters outbound network traffic and scans for API keys, tokens, and credentials using gitleaks to prevent secrets from leaking, ensuring your dev environment remains secure.

Can I use Multitui with my existing terminal applications?

Yes, Multitui apps complement your existing terminal setup like iTerm2, Ghostty, Alacritty, or Terminal.app. They are designed for tools that deserve their own dedicated window, helping to reduce terminal tabs and provide more control, while allowing you to keep your favorite terminal for general work.
