urPiano is a free online piano with a full 88-key keyboard playable by mouse, touch or computer keyboard. It supports sustain, note labels and octave shifting, and includes a learning mode where notes fall toward the keys Guitar-Hero style for popular songs, so beginners can play along immediately.
A built-in MIDI recorder lets players capture and replay performances directly in the browser, and recordings can be revisited later. Everything runs client-side, so there is nothing to install, no sign-up, and no latency from a server round-trip. It works on desktop and mobile browsers alike.
