Years ago Traccar had a very basic web interface, so many people wanted to integrate it with OpenGTS to get most OpenGTS features and support for wide range of protocols (from Traccar). Nowadays, Traccar has very good web interface by default, so there is much point in integrating it with OpenGTS. It's still an option though in case you want it for some reason.
Hello,
What's the benefit to integrat OpenGTS and Traccar ?
Regards
