Broadcast Input

Broadcast Input lets you type once and have your keystrokes sent to multiple terminal panes simultaneously. It is designed for tasks like deploying to a fleet of servers, running the same command across dev/staging/prod, or maintaining multiple nodes in sync.

Enabling Broadcast

1. Click the broadcast icon in the terminal toolbar, or press ⌘⇧B (macOS) / Ctrl+Shift+B (Windows/Linux)
2. The Select Broadcast Targets picker opens — showing all open terminal panes
3. Check the panes you want to receive keystrokes
4. Click Confirm — broadcast mode activates

A “Broadcast Enabled” banner appears at the top of each participating terminal pane.

Target Selection

The target picker lists every open terminal:

• SSH sessions (labeled with hostname)
• Local terminal panes (labeled “Local Terminal”)
• Select All / Deselect All convenience buttons
• Shows target count: “3 target(s)”
• The current (sender) pane is labeled “Current” and always receives input

Note

You can broadcast to a mix of SSH sessions and local terminals at the same time.

How It Works

When broadcast is active:

• Every keystroke in the sender pane is forwarded to all selected target panes via the same binary WebSocket channel
• Paste operations (including multi-line pastes) are also broadcast
• Each target processes input independently — if one target is slow, others are unaffected
• Targets can be in different split pane positions or on different tab pages

Disabling Broadcast

Click the broadcast icon again (now highlighted) or press ⌘⇧B to open the picker and deselect targets, or use Deselect All and confirm.

Closing any target pane automatically removes it from the broadcast group. Closing the sender pane disables broadcast entirely.

Use Cases

• Fleet deployments — run sudo systemctl restart myapp on 10 servers at once
• Environment parity checks — run env | grep APP_ on dev, staging, and prod to compare
• Synchronized log tailing — tail -f /var/log/app.log on multiple servers simultaneously
• Configuration rollouts — edit the same config file path on multiple nodes
• Cluster maintenance — run drain/cordon commands across Kubernetes nodes

Caution

Broadcast sends keystrokes immediately to all targets. Be careful with destructive commands — there is no confirmation step before broadcast executes on all targets.

Split Pane Integration

Broadcast works naturally with split panes. You can have a 2×3 grid of SSH sessions all receiving the same input, while viewing all outputs simultaneously — ideal for visually verifying that a command succeeded on every server.
