docktor vs DockDoor
docktor does the same live Dock previews DockDoor is known for, then keeps going: music with lyrics, calendar, weather, and system stats all live next to your Dock. Free, notarized, made for macOS 26.

Designed to look like Apple built it
Both apps preview your windows when you hover the Dock. The difference is feel: docktor is a native macOS 26 app built around Liquid Glass, so the panels, blur, and motion match the rest of the system instead of looking like a utility bolted on. And it doesn’t stop at previews — the space beside your Dock holds now-playing with lyrics, your calendar, the weather, and live system stats.
