The multiplexer engine forAgents.
RMUX keeps your shell alive, scriptable, and fully inspectable. Drop it in as a blazing-fast, tmux-compatible multiplexer, or use it as an engine for terminal-native automation with persistent sessions, snapshots, and typed orchestration. 100% Rust.
Natively available on Windows , macOS , and Linux .
Usable like tmux, automated like Playwright.
let rmux = Rmux::builder().connect_or_start().await?;
let session = rmux
.ensure_session(
EnsureSession::try_named("ci")?
.create_or_reuse()
.detached(true),
)
.await?;
let pane = session.pane(0, 0);
pane.send_text("printf 'test result: ok\n'\n").await?;
pane.wait_for_text("test result: ok").await?;
let snapshot = pane.snapshot().await?;
Install it your way.
