Unfortunatly, yes. Linx 5.13 was the last free version and since September 2018, and the updates will not be available for it further.
The server for the latest version of Linx is available for a trial of 7 days if you’d like. Normal price for the Server is $149 per month.
I’m going to ask our Marketing manager to contact you regarding pricing and options for demos.
Best regards,
