Use Cases
- Fleet and asset tracking for logistics, delivery and service vehicles.

Limitations and Considerations
- The web app relies on external map and reverse-geocoding providers; some services require separate configuration or subscriptions. (traccar.org)
- Demo servers do not have reverse geocoding or email pre-configured and are intended for evaluation only. (traccar.org)
Traccar is a production-capable GPS tracking solution suited for self-hosted deployments and commercial setups, offering extensible APIs and a full feature set for real-time telemetry and reporting. (github.com)
