switcharoo

A tiny macOS window switcher — Cmd+Tab, but it knows about windows.

Single Swift file, no dependencies, no Xcode project. Window lists are MRU-ordered; titles update live while the panel is open.

keys

key	action
Cmd+Tab / Cmd+Shift+Tab	quick mode — release Cmd to switch
Opt+Tab / Opt+Shift+Tab	search mode — type to filter
Up/Down · Ctrl+K/Ctrl+J · Tab	move selection

Cmd+M · Cmd+H · Cmd+Q · Cmd+Opt+Q	minimize · hide · quit · force-quit the highlighted app

URL scheme for Raycast/Alfred/scripts: switcharoo://show, switcharoo://quick, switcharoo://snap (renders the panel to /tmp/switcharoo-ui.png).

build

./setup-dev-cert.sh   # once — stable self-signed identity, so the
                      # Accessibility grant survives rebuilds
./build.sh            # compile, sign, relaunch

Requires macOS 14+ and the Accessibility permission (prompted on first launch). Cmd+Tab interception starts as soon as the grant lands.
