Nextcloud is an open–source, self–hosted content collaboration platform designed to give users full control over their data. It serves as a comprehensive alternative to proprietary suites like Google Workspace or Microsoft 365 by providing file storage, document editing, calendar synchronisation, and contact management. Because it is hosted on private servers – or through trusted European providers – it bypasses the risks associated with surveillance capitalism and large–scale data harvesting. The platform is highly modular, allowing for the integration of additional features such as end–to–end encrypted chat and task management. It is a robust solution for entities needing to comply with strict EU data protection regulations while maintaining a collaborative digital environment.
