GoKawiilUniversal Rust multiplexer for the agentic era: detachable, scriptable, and inspectable, with a tmux-compatible CLI, daemon-backed SDK, and native Ratatui integration. English · Français · 简体中文 · 日本語
Important Current release: v0.2.0, published on 18 May 2026. All 90 tmux-compatible commands are implemented, but bugs are expected — this is a fresh public preview. Please file issues if you hit one.
Why RMUX
RMUX exists because I believe the tmux use case has only been partially explored. My own starting point was simple: I wanted to run long-lived agents over SSH without losing their terminals, while still being able to inspect, script, and orchestrate everything around them.
So I rebuilt that idea from scratch in Rust: a blazing-fast, tmux-compatible multiplexer with a typed SDK, persistent sessions, structured snapshots, and native local transports on Linux, macOS, and Windows, including Windows Named Pipes. No WSL required.
RMUX is usable by agents, headless CLI workflows, and humans alike: you can give terminal apps detachable execution, reconnect later, inspect their state, drive them from code, or simply use it for normal tmux-style terminal work.
