Batty — a native macOS terminal multiplexer

Sessions · Panes · Tabs

One window. A sidebar of sessions, recursive horizontal and vertical splits, and tabs per pane with auto-derived titles.

Native AppKit performance

libghostty under the hood. Metal-accelerated rendering, true-color, ligature-friendly. No web view, no bridge tax.

Bell Feed

Every BEL and OSC 9 lands in a unified feed. Click an entry to jump to the originating tab. Per-session mute when a long build gets noisy.

Why Batty?

Ghostty's terminal engine is fast and faithful. tmux's structure<br>(sessions, splits, multiple windows of work) is unbeatable for<br>day-to-day terminal use. Batty pairs the two in a native macOS<br>shell — no tmux required, no web UI, no compromise on what a<br>terminal feels like.

If you've been hopping between Terminal.app, iTerm2, and tmux:<br>Batty is the third one you'd build if you had time.
