Your backup is only as good as the last time you updated it.
Every engineer running a main-and-backup rig knows the situation: you make a change on the main machine minutes before doors — a new cue, a swapped track, a fixed file — and there’s no time to copy it across. You tell yourself you’ll sync the backup later. Then the show starts. If the main goes down now, the backup takes over with yesterday’s show. This is the real risk in live production — not that a machine crashes, but that when it does, your backup isn’t current. Most engineers patch this by hand: dragging folders between machines, juggling general-purpose sync apps never built for show conditions, hoping nothing was missed. ShowSync exists so that never happens. It keeps your backup machine an exact, live mirror of your main — automatically, the instant anything changes — so the backup is always ready, and “did I update it?” is never a question again.
Built for live sound engineers, video operators, AV technicians, and broadcast engineers. One job: your backup is always show-ready.
General sync tools weren’t built for show night. Here’s how ShowSync compares.

The top rows are what ShowSync was built for. The bottom rows are where general-purpose tools cast a wider net — ShowSync stays focused on one thing: keeping your backup show-ready.
Bound to your network — on purpose.
A show Mac has many network paths: Wi-Fi, Thunderbolt Ethernet, audio-network ports. ShowSync locks sync to the one you choose, so it never strays onto the audio network or drifts to Wi-Fi mid-show. No other sync tool does this.
Built to survive the chaos.
Cables get kicked. Adapters get knocked loose. Backup machines get restarted. ShowSync rides it out — and reconnects on its own the moment the connection returns. Tested for stability through repeated unplugs and reboots, on machines running for weeks.
No cloud. No subscription. No surprises.
Activate once and ShowSync runs offline, forever — exactly what a show machine with no internet needs. One purchase, yours to keep. No monthly fee, no account required.
ShowSync doesn’t try to be every sync tool. It’s the one built for the moment it matters most — when the show is live and your backup has to be ready.
