number of devices

Good morning, I would like to know what maximum number of devices the tracar supports, without stopping or giving errors, that it works in a stable way. And if there is anyone here in the group who already has a considerable amount.

There is no limit. Traccar can handle as many devices as your server hardware can handle.

I know that there are some installations with 15k and more devices. Traccar has been tested with 100k emulated devices.

what is that installations ?

I don't think I understand your question.
