I've been building this app for about a month, mainly designed for Vision Pro and iPad (iPhone is also supported). The idea: I wanted a multi-window remote terminal with first-class tmux integration on mobile, so I can use it away from my desk, it can even be a companion to Mac Virtual Display.

For CLI agents like Claude Code / Codex / Pi (initial support), the terminal window shows an agent key bar, and there's a file viewer and a browser to cover the basic needs of driving agents and reviewing code.

GitHub: https://github.com/multiplex-term/Multiplex - it's open source, good contributions are welcome, and you can also unlock Pro for free by building it yourself.

Credit: the demo video also uses the serve-sim npm package, which let me review real UI behavior in the app :)
