OpenGTS vs Traccar: two open-source GPS servers

Short version. OpenGTS and Traccar are both Java, both Apache-2.0, both servers that take a tracker’s connection and turn it into positions on a map. Traccar decodes more than 200 protocols, shipped twenty releases in the last twelve months and has a documented REST API. OpenGTS’s last release is 2.6.7, dated 20 February 2020, and it bundles a short list of device modules. For a new deployment, Traccar; OpenGTS makes sense mainly where it is already running and doing its job.

We have compared both briefly alongside three other platforms. This is the longer head-to-head, with sources, checked on 6 October 2026.

OpenGTS vs Traccar at a glance

Project activity: the row that decides most cases

Traccar is busy. On GitHub it has 7.8k stars and 3.4k forks; since 6 October 2025 it has taken 696 commits, 97 of them in the last thirty days, and published twenty releases from v6.11.0 to v6.16.0 on 27 September 2026. Its forums hold about 19,300 topics, nearly 14,000 of them about the server.

Read one more number with that. Of the most recent hundred commits, 84 are by its creator, Anton Tananaev. That is a project with a very productive lead rather than a broad maintainer base, which is worth knowing if you are betting a business on it.

OpenGTS is quiet. Its own news page lists 2.6.7 in February 2020 and 2.6.6 in September 2018; the changelog has carried “2.6.8 [pending]” with nothing under it since. The SourceForge files page stops at 2.6.5, from October 2017. The SourceForge forums hold about 2,100 topics; the last post in the Help forum is from November 2022, and Open Discussion last saw a post in March 2026.

Quiet is not broken. Plenty of OpenGTS installs have run for a decade without needing anything. But a server that faces the public internet on several TCP ports, built against Java and Tomcat versions from that era, is a security question as much as a feature one.

Device and protocol coverage

This is where the usual description of OpenGTS, ours included, needs correcting. The open-source build ships device communication servers for TK102/TK103-style trackers, Astra Telematics, Sanav, TAIP, Aspicore, TrackStick and a handful of HTTP-based phone formats, plus a template for writing your own. Broader device support belongs to GTS Enterprise, GeoTelematic’s commercial product, where further modules are “separately priced binary add-on modules”.

Traccar’s device list covers Teltonika, Jimi IoT (Concox), Ruptela, Queclink, Suntech and the long tail of OEM firmwares, and it also decodes most of what OpenGTS bundles: TK102, TK103, Astra, Sanav and TAIP all have Traccar decoders. It even accepts the OpenGTS HTTP format that phone logging apps send.

If you have an exotic tracker that only an OpenGTS module speaks, that module is the reason to stay. Otherwise coverage favours Traccar by a wide margin.

Interface, accounts and white-labelling

OpenGTS’s web interface is the track.war servlet: account login, maps over OpenLayers, OpenStreetMap, Leaflet or Google, geozones with arrival and departure events, and reports from an XML report engine. It is dated to look at, but it was multi-account from the start: each account has its own users and devices, and the look can be customised to fit the company running it. For a small reseller that was, and is, a real feature.

Traccar’s web app is a modern React application. Its account model is a hierarchy rather than isolated tenants: managers can create users up to a limit, and devices are shared by permission. It has scheduled reports emailed on a calendar, and alerts for harsh driving, fuel drops and maintenance in the server itself, and native phone apps for managing devices and for turning a phone into a tracker.

Neither offers commercially classified trips, ranked driver scores or per-customer branding on reports out of the box. That layer is what the Traccar alternative post covers.

APIs and integration

Traccar has a REST API described by an OpenAPI file: devices, positions, geofences, reports, notifications, commands, 76 paths in all. A WebSocket at /api/socket streams devices, positions and events live. And the forwarder pushes decoded positions, generated events or raw protocol traffic to another system, which is what makes Traccar easy to put underneath something else.

OpenGTS offers events.war, a servlet that returns a device’s events as XML, JSON, CSV or GPX. It is a pull: you ask with the account, user and password in the query string. Event notification rules are a separately priced GTS Enterprise add-on. We found no outbound forwarder in the open-source build’s changelog or source.

Deployment

OpenGTS wants Java, Ant, Tomcat and MySQL, built from source: device servers run as separate Java processes, the web interface and the HTTP-based device servers run inside Tomcat. It is a manual install, and the FAQ still points at Tomcat 6 documentation for SSL.

Traccar ships installers for Windows and Linux and official Docker images tagged for every release. It defaults to an embedded H2 database that its own documentation does not recommend for production; switch to PostgreSQL or MySQL on day one. If you would rather not run it at all, hosted plans start at $9.95 a month. Past a few thousand devices the questions change; scaling Traccar covers that.

When to choose OpenGTS

• It is already running, it does what your users need, and nothing on your roadmap requires a change.
• You depend on a device module that OpenGTS has and Traccar does not.
• You want a commercial path with the same codebase, and GTS Enterprise’s add-ons are the ones you need.
• You value its account-per-customer model and per-domain look, and are prepared to own the patching.

If you keep it, treat it as software you maintain yourself: put it behind a firewall where you can, keep Java and Tomcat patched, and read the changelog as the last word you will get from upstream.

When to choose Traccar

• Any new deployment. Coverage, activity, documentation and API all point the same way.
• You need a REST API or a push feed into another system.
• Your hardware is anything mainstream from the last decade.
• You want the larger community: forum answers and existing configs for your exact tracker.

Where Routly fits

Routly reads from Traccar, not from OpenGTS. It has no device decoders of its own; it takes positions from Flespi, from Traccar’s forwarder, or from any gateway that POSTs JSON to its generic webhook. On top it adds trip classification, fuel-drain detection, driver scoring, scheduled CSV, Excel and PDF reports, and isolated organisations for each customer.

There is no OpenGTS connector, and we will not pretend the generic webhook makes one unnecessary. Because OpenGTS does not push, an OpenGTS user has two honest routes:

1. Move the trackers to Traccar. Most of the hardware OpenGTS supports, Traccar decodes, and each protocol’s port is configurable. It means changing each device’s server address, so it is a migration rather than a setting.
2. Write a small poller. Read new events from events.war or the MySQL event table and POST them as JSON to Routly’s generic webhook. That works, and it is code you write and own.

If either sounds like more work than you want, keep OpenGTS. You can try the layer above in the demo, no account needed; the comparison hub has the other head-to-heads.

Frequently asked

Is OpenGTS still maintained?

Its last release is 2.6.7, from February 2020, and the changelog’s next version has been marked pending since. The forums still see the occasional post. Call it stable at best, unmaintained at worst.

Can Traccar replace OpenGTS without new trackers?

Usually. Traccar decodes TK102/TK103, Astra, Sanav and TAIP among its 200-odd protocols. The trackers stay; their server address changes.

Is OpenGTS or Traccar better for multiple customers?

OpenGTS has separate accounts built in. Traccar has managers with user and device limits. Neither isolates customers the way a multi-tenant platform does; that is a job for a layer above.

Are both free for commercial use?

Yes. Both are Apache-2.0, which lets you modify, resell and keep your changes private.

What is GTS Enterprise?

GeoTelematic’s commercial product built on OpenGTS, with more reports, a rules engine and extra device modules priced separately.
