V0.1 — PUBLIC PREVIEW
The Rust Multiplexer for Agents.
RMUX keeps terminal work alive, scriptable, and inspectable. Usable as a tmux replacement from the shell, and drivable from Rust through sessions, windows, and panes.
Natively available on Windows , macOS , and Linux .
Usable like tmux, drivable like Playwright.
rust 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("cargo test\n").await?;
pane.wait_for_text("test result: ok").await?;
let snap = pane.snapshot().await?;
