The first NINJAM client with live video. Real-time online jamming with HD video of every musician in the room.
See every musician you're jamming with in HD, perfectly synchronized to the audio interval. HDMI output, fullscreen, auto-quality.
For 20 years, NINJAM only carried audio. We designed a video extension that rides the same interval clock, the same transport, and the same synchronization GUIDs as the audio — so video can never drift from what you hear.
The protocol is public, open source.

NINJAM (Network Jam) was created by Cockos in 2005. Instead of fighting network latency, it embraces it: everyone plays along to a shared metronome, and you hear what others played in the previous interval. The result is a surprisingly natural and creative way to make music together.
NinjamZap is an independent client — not affiliated with Cockos or the official NINJAM project. The core audio engine is open source under GPL v3 at github.com/jacinside/ninjamzap-core.
Works with any standard NINJAM server. Live video is a NinjamZap extension — other clients ignore it and audio still works for everyone.
NinjamZap is available for free on the App Store.

⚠️ Audio latency depends on your phone's audio hardware. On older/budget devices the built-in mic adds noticeable capture latency — even with wired headphones, since that's the input path, not the output — and USB interfaces can be unreliable. For tight timing use a recent mid/high-end phone (Pixel 6+, Galaxy S22+, OnePlus 9+, ROG Phone) or a USB audio interface.
