Our verdict on Polyfence
Polyfence provides geofencing for mobile applications, IoT hardware, and server software. Developers can create circle or polygon zones, then detect entry, exit, and dwell events. Evaluation can run locally through mobile SDKs, on IoT hardware through an embedded C library, or on servers through a REST API. Its documented use cases include fleet and delivery operations, agriculture, perimeter security, compliance, retail, and personal safety. Small and mid-market teams building across mobile, Linux, API, or self-hosted environments are the clearest fit.
Pricing is straightforward: Polyfence is free during Early Access, and the documentation states there is no zone-count limit during that period. The product has no paid tiers to compare, so teams can assess its capabilities without a license fee. Its feature set also includes GeoJSON zone import and persistence of zone definitions and state across app restarts. Adaptive GPS polling can respond to movement, activity, zone proximity, and battery state, giving developers controls for location-heavy applications where polling behavior matters.
Deployment flexibility is a central strength. Polyfence supports cloud, self-hosted, and mobile deployment, with Linux and API access alongside iOS and Android platforms. The main trade-offs are its Early Access status, email-and-documentation support model, and the absence of web geofencing in its category specification despite a web platform listing. Teams needing a focused geofencing layer across devices and servers should consider Polyfence; organizations requiring a mature release process, broader support channels, or browser-native geofencing should evaluate alternatives.
