Details

Rmux is a general-purpose, Rust-based terminal multiplexer designed for agent-centric workflows. While retaining the functionality of traditional tmux, it provides powerful features that let AI agents programmatically manipulate the terminal environment.

Key Features and Characteristics:

  • Playwright-Style SDK: Provides a type-safe SDK that lets agents create, inspect, and script terminal sessions.
  • Agent Orchestration: Enables agents to launch terminal apps, check status, and build environments they can directly control via code.
  • tmux Compatibility: Supports 90+ tmux commands, so existing users can use it just as comfortably.
  • Multi-Platform Support: Works natively on Linux, macOS, and even Windows (via Named Pipes) without WSL.

Beyond simple terminal management, this tool is expected to be useful infrastructure for developers looking to implement inter-agent communication, broadcasting, and complex automation workflows in multi-agent environments.
