Why Space?
Because your thumb is already there.
Tap Space to type normally. Hold it to open your shortcut layer. SpaceLauncher tells the difference . The catch: when you type fast, the next key often goes down before Space comes back up. General tools like Karabiner, Hammerspoon, and Keyboard Maestro can approximate pieces of that timing. SpaceLauncher is built around it.
What if I forget?
Hold Space and look. SpaceLauncher shows what you can press next.
Actions you use often become less prominent, so the ones you still need help with stand out. Follow the visible command tree from Spacebar F, then D, and Downloads opens.
Where SpaceLauncher Fits
Spotlight, Raycast, Alfred, and LaunchBar are built for finding things. SpaceLauncher is built for the actions you already repeat every day. It grew out of years of using those tools. Read the story behind the app.
Bring your own leader
Space is the default, but it does not have to be the only leader. If you've already trained a leader -- Caps Lock, a Hyper key, F12, even a key picked by its raw key code -- hold or tap that instead. SpaceLauncher works the same behind any of them. See the guide.

Trust
Privacy
SpaceLauncher needs Accessibility access to see your keystrokes — there’s no way around that; it’s how anything built on the Space key works. What you type stays on your Mac — and you’re free to verify SpaceLauncher’s network traffic anytime with Proxyman, Charles, or Wireshark.
Built to last
Your setup is not locked away. You can export your config as documented, human-readable JSON, then parse it, migrate it, diff it, or script against it.
SpaceLauncher also keeps local rolling, timestamped backups so a damaged configuration can be recovered. When you save shortcuts, conflict detection warns about exact sequence and prefix conflicts before they become surprises.
