Nextcloud – Self-Hosted Cloud Storage Platform

Introduction to Nextcloud

Nextcloud is a free, open-source, self-hosted cloud storage and collaboration platform that provides functionality similar to Dropbox, Google Drive, and Microsoft OneDrive. By running Nextcloud on your own server or trusted hosting provider, you maintain complete control over your data without relying on third-party cloud services. This makes Nextcloud an excellent choice for individuals, businesses, and organizations that prioritize data sovereignty and privacy.

Beyond file storage and synchronization, Nextcloud offers a comprehensive suite of productivity and collaboration tools including calendar, contacts, email, video conferencing, document editing, task management, and more through its extensive app ecosystem. The platform supports end-to-end encryption, two-factor authentication, and detailed sharing controls.

Key Features

Nextcloud provides file synchronization across devices, real-time collaboration on documents, calendar and contact management, audio/video calls (Nextcloud Talk), email integration, and extensive third-party app support. Security features include end-to-end encryption, server-side encryption, brute force protection, and comprehensive audit logging.
