A lightning-fast, open-source app workspace manager for macOS. Save and restore your entire app configuration in seconds.

docki replaces manual app switching with instant workspace presets.

I built this because I was tired of manually switching between different work contexts. Now I save each setup as a preset and switch instantly with a single command.

Perfect for:

• Switching between different work contexts
• Context-switching between projects
• Keeping your dock clean by only running what you need

Prerequisites: Zig 0.15.2+

git clone https://github.com/yourusername/docki.git
cd docki
zig build -Doptimize=ReleaseSafe
./zig-out/bin/docki --version

brew install docki

Capture your currently running applications:

docki save work
docki save creative
docki save focus

This saves the names of all running apps to ~/.config/docki/presets/{name}.apps

Restore a saved workspace:

docki load work

This will:

• Launch any apps in the preset that aren't running
• Quit any apps that are running but not in the preset (except protected apps)
• Leave protected apps untouched (Finder, Terminal, iTerm2, ghostty, Warp, Alacritty)

docki list

Shows all saved presets:

work
creative
focus

docki --help          # Show usage
docki --version       # Show version

Create ~/.config/docki/config.json to prevent certain apps from being quit:

{
  "protected_apps": ["Finder", "Terminal", "iTerm2", "ghostty", "MyCustomApp"]
}

Protected apps will never be automatically quit when loading a preset. App names are case-insensitive (you can write them in any case, they'll be matched regardless).

docki uses AppleScript (via osascript) to:

• Query running foreground applications
• Launch applications by name
• Quit applications gracefully

Presets are stored as simple text files with comma-separated app names.

Build and test locally:

zig build run -- save test_preset
zig build run -- list
zig build run -- load test_preset

Run tests:

zig build test
