PianoDuo is a project by Daniel O'Dea, constructed in spare time. If you like PianoDuo and want to help cover hosting costs and encourage further development, please consider buying me a coffee.

What does this do?

PianoDuo is a tool to play music either solo or with other people online. You can use your computer keyboard to play notes, click with a mouse, use a MIDI keyboard, or use touch gestures on a tablet or mobile.

How do I invite friends?

Send them the URL to play together.
