OSC Messaging

OSC Messaging keeps theatre and live-event teams in sync with fast, channel-based chat, live intercom, and OSC show control - all running entirely on your local Wi-Fi. No server, no accounts, no internet, no cloud.

Originally developed as a way for Front of House sound to chat with backstage about wireless mic issues, patching, and everything else that comes up during a show.

How it works

• Open the app on every device on the same Wi-Fi network - they find each other automatically
• Organize conversations by department channel (Audio, Lights, Deck, Props, Video, FOH)
• Talk live on per-channel intercom party lines with push-to-talk, or send voice clip messages
• Share photos, set per-channel notifications, and use quick replies
• Send and receive OSC from consoles and show-control software
• Use a Mac as a bridge into your existing wired comms system
• Show your Wi-Fi join QR code so new devices can hop on fast

Messages never touch the internet - they stay on your network and disappear when everyone leaves. If you're not on the Wi-Fi, you're not in the show.
