Nextcloud is a powerful open-source platform for file storage, collaboration, and productivity; positioned as an ethical alternative to cloud suites like Google Workspace, Microsoft 365, or Dropbox. It allows individuals and organisations to host their own private cloud, offering tools for document editing, calendar management, video calls, chat, and email integration. Built around open standards and data sovereignty, Nextcloud puts users in full control of their information while maintaining usability and scalability comparable to major commercial cloud services.
