Before you switch
Document tools are about compatibility: test importing a real file and exporting it in the formats you share. For content management, check the editor experience and plugin ecosystem before migrating a whole site; a trial with one section usually reveals everything.
Like every project listed on SelfHosted, Nextcloud Office is developed in the open — you can read the code, follow development, and even contribute. Check the system requirements and the project’s own documentation linked on this page before installing.
