In a world dominated by Google Drive, Dropbox, and OneDrive, privacy-conscious users are seeking more control over their data. The solution? Build your own personal cloud using open-source tools.

💡 Choosing the Right Hosting

To build a personal cloud using open-source tools, you have two main options:
