eXo is free to use in the cloud or available as a 30-days trial on premise. Support with guaranteed SLA's is not provided for the Free Access Plan. In addition, we will continue to add and improve features, documentation, performance, or make other changes based on user feedback. You might notice these changes or encounter minor issues; if so, please let us know so we can fix them for you. We will notify you of any planned downtime for upgrades, but there is still a chance of unplanned downtime as well.
