A truck enters a delivery zone. A field worker arrives at a job site. A device leaves an authorized area. In most systems, those events either disappear into a location feed or require custom infrastructure to turn into something useful.

SpatialFlow is built to close that gap.

What SpatialFlow Does​

SpatialFlow turns real-world movement into automated workflows. Draw a geofence, connect a device, and trigger actions when that device enters, exits, or dwells inside an area. Send a webhook, notify a team, update a system, or log an event without building geospatial event infrastructure yourself.

Here is a concrete example: a field technician drives to a job site. When their phone enters the job-site geofence, SpatialFlow fires a workflow that sends a webhook to your dispatch system, posts an arrival notification to Slack, and logs the timestamp for compliance. No manual check-in. No custom code.

That is the idea behind "the Zapier of geospatial events." You define the boundaries. You define the actions. SpatialFlow connects them.

Core Capabilities​

Real-time geofencing. Draw geofences on a map and receive instant notifications the moment a device enters, exits, or dwells within a defined area. Geofence checks use PostGIS spatial queries for reliable, scalable event processing.

Workflow automation. Build workflows visually that trigger on geofence events. Chain together conditions, delays, and actions: send a webhook, dispatch an email, update a record. No custom code required.

Device tracking. Track device locations across your workspace in real time. The dashboard gives operations teams a live view of where everyone is, and the mobile app keeps field workers connected.

Webhook integrations. Connect SpatialFlow to any system that accepts HTTP. When a geofence event fires, SpatialFlow delivers a structured payload to your endpoint with retries and delivery logs so developers can debug what happened.

API and developer tooling. A full REST API with beta SDKs for Python, Node.js, and Go. Web dashboard, iOS app, and Android app for teams in the field.

Example: Vehicle Enters a Delivery Zone​

1. Draw a geofence around your warehouse or delivery area.
2. Connect a device: a mobile phone, GPS tracker, or fleet vehicle.
3. Create a workflow that listens for geofence_enter events.
4. Trigger actions: send a webhook to your dispatch system, fire a Slack notification, or log the event.
5. Review delivery logs to confirm the event was processed and the webhook was delivered.

The entire setup takes minutes, not sprints. The Quick Start Guide walks through it step by step.

Who SpatialFlow Is For​

Developers who need geofence-triggered webhooks without building location infrastructure from scratch.

Ops teams that need alerts when vehicles, workers, or assets enter or exit important areas.

Product teams building location-aware apps that need event history, delivery logs, and workflow automation baked in.

How It Is Built​

SpatialFlow is built to handle bursts of location updates. Geofence events are processed asynchronously, dashboards update over WebSockets in real time, and webhook deliveries include retries and logs so developers can debug exactly what happened and when.

The platform runs on AWS with auto-scaling, so it handles spikes in location data without manual configuration.

Why We Built It​

Every location-aware product eventually needs the same infrastructure: geofences, event detection, workflow triggers, webhook delivery, device management, audit trails. Teams rebuild this stack over and over, or cobble together scripts and cron jobs that break under load.

We built SpatialFlow so teams can skip that work and go straight to the automation that matters to their business.
