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.

See RMUX in action through concrete terminal automation workflows.

Usable like tmux, automated like Playwright.

CLI 
rmux new-session -d -s ci
rmux send-keys -t ci "printf 'test result: ok\n'; rmux wait-for -S ci-done" Enter
rmux wait-for ci-done
rmux capture-pane -p -t ci
Rust SDK 
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?;

When the keyboard is the user, tmux still fits. When code is the user, RMUX takes over.

Create a session. Keep it running. Return anytime.
