Features
Everything you need to play piano online with friends.
Real-Time Multiplayer
Every note you play is heard by everyone in the room within milliseconds. PianoFlow uses WebSocket connections with binary batching and Web Audio scheduling to deliver low-latency, jitter-free playback — even with dozens of simultaneous players.
MIDI Keyboard Support
PianoFlow supports the Web MIDI API. Connect any USB or Bluetooth MIDI controller. Full velocity sensitivity and sustain pedal support are included, so you can play with the same expressiveness as a real instrument.
Private & Public Rooms
Create a password-protected room for a private jam session, or join the open lobby to play with anyone online. Each room has its own chat, user list. Room hosts can kick or ban disruptive players.
Built-In Chat
Text chat with emoji support is available in every room.
