RMUX is a universal terminal multiplexer written in Rust, designed as a tmux-compatible alternative with a typed SDK, daemon-backed architecture, and native support for Linux, macOS, and Windows (including Windows Named Pipes, no WSL required). It exposes three surfaces: a `rmux` CLI, a `rmux-sdk` Rust crate, and a `ratatui-rmux` widget, all sharing a single local IPC protocol. Key features include detachable sessions, structured pane snapshots, scriptable automation, and native Ratatui integration for building TUI apps. The project targets agentic workflows — running long-lived AI agents over SSH, orchestrating multi-agent terminals, and driving CLI/TUI apps programmatically from code. Currently at v0.2.0 (public preview), all 90 tmux-compatible commands are implemented.
