Polyfence is in Early Access — APIs and limits may still change. Your feedback shapes what we build.

What can you build with Polyfence?

Polyfence is the geofence layer. Build a product on top, or use a reference tracker as-is. Same platform, two on-ramps.

Both

Fleet & delivery

Know the moment a vehicle reaches a depot, a customer site, or a restricted area — without streaming GPS or draining batteries. Define your delivery regions once; entry and exit fire as events, and zones stay current as routes change.

Livestock & agriculture

Know when your animals stray past a paddock or into a restricted area — even where there's no signal. Geofencing runs on the device itself, offline; your zone changes sync the moment connectivity returns.

Perimeter security

Map your protected perimeters and get an alert the instant a boundary is crossed — sub-second, on-device. Give each team its own keys so sites stay cleanly separated.

Compliance zones (low-emission, congestion)

Warn drivers the moment they enter a low-emission, congestion, or restricted zone — before it costs them a fine. Regulatory boundaries stay mapped and update automatically when the rules change.

Retail, tourism & events

Trigger the right content, offer, or action the moment someone steps into a place that matters — a store, a venue, a landmark. You draw the zones; we handle the platform-specific plumbing, so you're not building geofencing from scratch.

Family & personal safety

Know when your kids reach school, get home, or leave a trusted place — a quiet heads-up, not constant tracking. It runs quietly in the background and barely touches the battery.
