All ONLYOFFICE Developer Edition license types include Document Editor Spreadsheet Editor Presentation Editor One year updates and support White Label option Frequently Asked Questions What do the 'lifetime license' and '1-year updates' mean? You can use all the ONLYOFFICE Development Server features available at the moment of the purchase for an unlimited period of time, but one year after the purchase date you will no longer be able to get free updates. If you want to update your ONLYOFFICE Development Server version later, you will need to purchase a new license key. Single Server and Cluster licenses must be prolonged each year. What does the 'simultaneous connections' mean? We specified the maximum number of documents that can be edited at the same time. When the maximum value is reached, each next document will open in read-only mode. What if I want to provide my customers with ONLYOFFICE desktop and mobile applications under my own brand?
