    Comments about Nextcloud as an Alternative to Microsoft OneDrive
    Comment summary: Nextcloud is valued for its self-hosting capabilities, offering privacy and control over data. Many users appreciate its open-source nature, detailed customization, and vast plugin support. Criticisms include the complexity of setup compared to Microsoft OneDrive, making it less accessible for non-technical users. While Nextcloud's self-hosting provides a high level of trust and data privacy, some view it as impractical for those lacking resources to manage their own servers.

    With Nextcloud you control your own data, you are limited by your own hardware and don't have to trust Microsoft with your data.
