Self-hosted geofencing API

Most geofencing platforms are SaaS-only: you send location data to their servers, they run the trigger logic, and you receive events back through their API. That works fine until the questions that matter start showing up — where does our location data actually live, what happens to it after 90 days, what's our per-event cost look like at 10x our current volume, and what happens to our integration if the vendor changes their pricing tiers.

Fencemaker takes a different starting point: geofencing infrastructure you deploy on servers you control. Same core capability — polygon and radius zones, real-time enter/exit/dwell triggers, webhook delivery — but running on your own infrastructure instead of a third party's.

What self-hosting actually changes

Data stays where you put it. Location events, device history, and zone definitions live in your own database. There's no vendor retention policy to audit or renegotiate — you set retention rules directly.

Cost scales with your infrastructure, not your event volume. Hosted geofencing platforms typically price per tracked device or per API call, which means growth and cost move in the same direction. A self-hosted deployment's cost is tied to the server it runs on, not the number of geofence triggers it processes.

You're not exposed to a vendor's roadmap. If a hosted provider changes pricing tiers, deprecates a feature, or gets acquired, your integration is at the mercy of that decision. Self-hosted infrastructure means the only roadmap that matters is yours.

How it fits into your stack

POST https://your-app.com/webhooks/fencemaker
{
  "event": "geofence.enter",
  "zone_id": "zone_warehouse_east",
  "device_id": "device_4471",
  "timestamp": "2026-08-18T09:00:00Z",
  "coordinates": { "lat": 40.7128, "lng": -74.0060 }
}

Fencemaker runs as infrastructure alongside the rest of your stack — deploy it on the same servers as your application, wire up Slack or Telegram for ops alerts, and start defining zones through the ops portal without writing custom code for the trigger logic itself.

What you get out of the box

• Polygon and radius-based zone definitions
• Real-time enter/exit/dwell webhook triggers
• Native Slack and Telegram webhook delivery
• Device tracking with dwell-time detection
• An ops portal for managing zones without touching code
• Full control over deployment, retention, and infrastructure cost

If the questions your team keeps circling back to are about data residency, cost predictability, or vendor risk, those are self-hosting questions — and they're the reason Fencemaker is built this way from the ground up.
