Open Source GPS Tracking Software

Open source GPS tracking software is vehicle tracking software whose source code is published publicly, so anyone can read it, modify it and run it on their own server without paying a license fee. The best known projects are Traccar, OpenGTS and OwnTracks. All are self hosted, meaning location data stays on infrastructure you control. The trade is that you supply the server, the setup, the branding, the reporting and the support yourself.

For vehicle fleets, Traccar is the most capable. It decodes more than 200 GPS protocols covering over 2,000 device models, runs on any major SQL database, and includes a REST API and mobile apps. OpenGTS is a strong second if your team works in Java and you want its XML based custom reporting. OwnTracks is excellent but is built for personal and family location tracking rather than fleets, so it is not a fair comparison to the other two.

The license is free. The system is not. You pay for the server, for the engineering time to install, configure and secure it, for writing decoders when a client brings an unsupported tracker, for building branding and billing, and for the hours your team spends supporting customers with no vendor to escalate to. For an in house fleet with a developer already on payroll, that cost is small. For a company selling tracking, it usually exceeds the cost of a commercial license within the first year.

In most cases yes. Traccar and OpenGTS are both released under the Apache License 2.0, a permissive license that allows commercial use, modification and redistribution, including inside your own closed source product. You must retain the original copyright and license notices and state what you changed. Copyleft licenses such as GPL and AGPL also allow commercial use but require you to publish your modified source, and AGPL applies that even when users only access the software over a network. Always check the license on each repository before building on it.

Traccar is released under the Apache License, Version 2.0, across both its Java back end server and its web interface. Apache 2.0 is a permissive license, so you may use it commercially, modify it, and keep your modifications private. It also disclaims all warranty and liability, which means there is no legal recourse against the project if something goes wrong in production.

Technically the tracking engine is excellent and many small tracking companies do run on it. What it does not give you is a business: there is no per client branded portal, no invoicing, no support contract to sell, and no one to call when a customer fleet goes dark. Those pieces are months of development, and they need maintaining afterwards. If you have the engineering capacity, Traccar is a genuinely good foundation. If you would rather spend that time selling, a supported platform is the faster route.

If you want to stay self hosted but skip the build, AIQ Connect is the closest equivalent. It installs on your own server so you keep the data ownership that makes Traccar appealing, and it adds white label branding, client portals, built in billing, more than 60 reports, support for over 1,000 device models and a named support team. If you would rather stay on open source, GPSWOX and Flespi are sometimes compared to Traccar, but neither is open source, so check what you are actually buying.

No, and it does not claim to be. OwnTracks is a privacy first personal location tracker. Its apps publish position from a phone over MQTT or HTTP to a self hosted backend called OwnTracks Recorder. It has no concept of vehicles, drivers, trips, geofence rules for a fleet, or billing, and it does not decode hardware GPS tracker protocols at all. It is the right answer for keeping a private location history or sharing your position with family, and the wrong answer for tracking a fleet.

Traccar supports more than 200 protocols and over 2,000 device models, covering most mainstream trackers including Teltonika, Concox, Queclink, Meitrack and Coban units. OpenGTS supports more than 100 protocols from makers including Queclink, Concox, Teltonika and Sinotrack. Before buying hardware, check the device is on the project supported list, because adding an unsupported protocol means writing and testing a decoder yourself.

A modest Linux server handles a surprising amount. A well tuned machine with around 8 GB of RAM can typically handle roughly a thousand devices reporting every 30 seconds, though this varies with reporting frequency, how much history you keep and how many sensors each vehicle carries. You will also need Java for Traccar or OpenGTS, a SQL database, a public IP address, open ports for each device protocol, and someone comfortable with Linux administration, certificates and backups.

No. GpsGate, Wialon, Navixy, GPSWOX and Flespi are all commercial platforms. They turn up in open source searches because some offer free tiers or self hosted deployment options, but their source code is not public and you cannot legally modify or redistribute it. Self hosted and open source are two different things: self hosted describes where software runs, open source describes whether you can see and change the code.

AIQ Connect is self hosted but not open source. It installs on your own server, so your fleet and client data stays in your database exactly as it would with Traccar or OpenGTS. The difference is that it arrives finished: white label branding, client portals, billing, more than 60 reports, support for over 1,000 device models and a support team are included rather than built by you. You trade source code access for time to market and a contract with someone on the other end of it.
