Yes, we offer a 15 days free trial period to all our users. Within this period you can test our features (except the BigQuery and Data Studio Integration features) without any limitations.
If you want to make use of our BigQuery and Data Studio integration features you will need to be a paying customer since they require custom work on our end. In case these are the only features you want to use our service for, please reach out and we will discuss if we can arrange a custom trial period for you.
