Does Cue Light work over the internet?

Yes. Cue Light is cloud-native and works over the public internet. The signal routes through Cloudflare's global edge network — director and talent can be in different rooms, different buildings, or different cities.

How it works technically

When the director taps a button in Cue Light, the signal is sent to a PartyKit server running on Cloudflare Workers. All connected display devices receive the update in real time — typically under 100ms. There is no local server, no VPN, no tunneling required.

What this means in practice

• Your speaker on stage connects over the venue WiFi or their own cellular data
• A remote guest on Zoom opens the display link in a browser tab — they're connected over the internet just like any website
• A second shooter at a wedding connects over their phone's cellular connection — venue WiFi is irrelevant
• A satellite church campus connects from a different city — same room code, different location

How this differs from hardware tally

Hardware tally lights and most software solutions (including Tally Arbiter) broadcast over your local network only. The moment a device is off your local WiFi — a remote guest, a different building, cellular data — the tally stops working. Cue Light has no local network dependency at all.
