A lightweight tool for persisting terminal process sessions

About

• A tool that keeps terminal sessions alive and allows reattaching, so work can continue without interrupting processes
• Provides only session persistence, without the complex window management features of tmux or screen
• Maintains sessions based on PTY processes, and supports connection control via attach/detach without ending the session
• Multiple clients can connect to the same session simultaneously; previous output state and terminal scrollback are restored automatically
  • Uses the libghostty-vt library to quickly restore terminal state when reattaching to a session
• The current session name is available via the ZMX_SESSION environment variable, supporting shell prompt customization
• Stores CLI and per-session logs under /tmp/zmx/logs/
• Works on macOS and Linux; does not provide windows, tabs, or splits
• Built with the Zig language (v0.15) and distributed as a single executable
