Introduction
Traccar is a mature open-source GPS tracking system written in Java. It supports over 200 GPS tracking protocols and communicates with a wide range of hardware devices. Organizations use it for vehicle fleet management, personal asset tracking, and logistics monitoring with full control over their data.
What Traccar Does
- Receives position data from 200+ GPS device protocols over TCP and UDP
- Displays real-time device positions and historical tracks on an interactive map
- Generates reports on trips, stops, speed, fuel consumption, and events
- Sends notifications via email, SMS, or push for geofence entries, speed alerts, and more
- Manages users, device groups, and permissions with multi-tenant support
Architecture Overview
Traccar is a Java application built with Netty for high-performance network I/O across dozens of concurrent device protocols. Position data is stored in an embedded H2 database by default, with support for MySQL and PostgreSQL for production deployments. The web frontend is a React application served by the same Java process. A REST API exposes all server functionality for integration with external systems.
Self-Hosting & Configuration
- Run via Docker, the official Linux/Windows installer, or as a standalone JAR
- Configure the database connection in
traccar.xmlfor MySQL or PostgreSQL - Open the required TCP/UDP ports for each GPS protocol your devices use
- Set up geofences, notification channels, and computed attributes in the web UI
- Use the companion Android or iOS app as a personal tracker
Key Features
- Broadest protocol support of any open-source tracking platform
- Geofencing with polygon and circular zones triggers configurable alerts
- Driver behavior analysis detects harsh braking, rapid acceleration, and idling
- Multi-tenant architecture supports separate user accounts with device isolation
- REST API enables full integration with ERP, fleet, and logistics systems
