  • Privacy-Focused
    CalyxOS emphasizes user privacy by minimizing data collection and incorporating features like encrypted communications and privacy-respecting apps.
  • Security Enhancements
    Built on top of Android, CalyxOS includes additional security features such as verified boot and regular security patches to protect against vulnerabilities.
  • De-Googled Experience
    CalyxOS removes most proprietary Google software, providing a de-Googled experience for users who prefer not to have their data collected by Google services.
  • Compatibility with Android Apps
    CalyxOS supports F-Droid and Aurora Store, allowing users to install a wide range of open-source and Android apps while maintaining user privacy.
  • Regular Updates
    The OS receives regular updates to ensure that the latest security patches and features are available to users, helping to keep devices secure.
  • User Control
    CalyxOS provides users with a high level of control over their device's settings and permissions, enabling them to fine-tune their privacy and security.

Possible disadvantages

  • Limited Device Support
    CalyxOS is only available for a relatively small number of devices, which limits its accessibility for users with different hardware.
  • Learning Curve
    Users who are accustomed to the traditional Android experience may face a learning curve when adapting to CalyxOS's different features and settings.
  • App Compatibility
    Some mainstream apps that rely heavily on Google services may not function as intended or may require additional configuration to work properly on CalyxOS.
  • Limited Official Support
    The level of official support and resources for troubleshooting might be limited compared to mainstream operating systems, potentially making it harder for some users to resolve issues.
  • Fewer Pre-Installed Apps
    While this is a benefit for those seeking a minimalist experience, some users might miss the convenience of having commonly used apps pre-installed.
  • Database Cleaner
    Schedule regular optimization and cleaning of the WP database to improve site performance. Pro adds options to manually clean individual DB tables, track unused options, and remove autoload bloat from the Options table.
  • Heartbeat Control
    Modify the WordPress Heartbeat API interval to reduce server load and improve the editor experience.
  • Disable Emojis
    Remove all emoji-related styles and scripts from the site.
  • Block Failed Login
    Limit failed login attempts and block bad actors from carrying out brute-force attacks. Pro adds options to customise the lockout duration, a full lockout mode, and the ability to hide the login form during lockout.
  • Two-Factor Authentication
    Enable two-factor authentication (TOTP) for all your users. Pro adds options to make 2FA compulsory for defined user roles, block users without 2FA from logging in, and allow users to save trusted devices.
  • Custom Login URL
    Hide the wp-login.php URL and create a custom secret login URL for your users.
  • Post Cloner
    Easily clone posts and any other post type, including all post meta and taxonomies.
  • Content Refresh
    Easily keep your content updated for SEO. Clone a post as a draft child. When you (re)publish the clone it updates the original post — perfect for refreshing old content without creating a new URL.
  • XML Sitemap
    Configure and manage the native WordPress XML sitemap for search engines. Pro adds sitemap caching for improved performance and a Google News sitemap.
  • Limit Image upload size
    Set a maximum file size for image uploads to stop users from uploading oversized files.
  • Custom Fields Builder
    Build a custom fields layout and create fields for any post type. Show or hide fields based on post type, post status, user role, and more.
  • Disable Gutenberg Editor
    Disable the block editor and restore the Classic editor as the default.
  • SMTP Email
    Replace the default WordPress mailer with an external SMTP service to ensure reliable email delivery.
