Features and specs

What each product offers, as listed by its team.

Flarum 5 features
CloudLinux 5 features
  • Modern Design
    Flarum features a sleek, user-friendly interface designed for modern web aesthetics and accessibility. This makes it appealing and easy to use for community members.
  • Extensibility
    Flarum is highly extensible with a robust plugin system, allowing users to customize and expand its functionalities via extensions created by the community or custom-developed.
  • Fast Performance
    Built with performance in mind, Flarum is lightweight and optimized for speed, ensuring a smooth user experience.
  • Mobile Friendly
    Flarum is fully responsive, allowing for seamless use across various devices, including tablets and smartphones.
  • Open Source
    Flarum is an open-source project, which means you can contribute to its development, audit its code, and use it without licensing fees.

Possible disadvantages

  • Early Development Stage
    Flarum is still relatively new and in continuous development, which might mean encountering occasional bugs or missing features that are available in more mature platforms.
  • Limited Documentation
    Documentation is still growing, and there may be gaps that can make it challenging for new users or developers to fully utilize all features or develop new extensions.
  • Smaller Community
    Compared to more established forum software, Flarum has a smaller user and developer community, which can result in fewer available resources, themes, and extensions.
  • Hosting Requirements
    Flarum requires a modern hosting environment with PHP and Composer support, which might not be available with all web hosts and can complicate the setup process for non-technical users.
  • Learning Curve
    Due to its modern architecture and use of Composer for extensions, there is a steeper learning curve for users unfamiliar with these technologies.
  • Enhanced Server Stability
    CloudLinux uses its lightweight virtualization technology (LVE) to isolate each tenant on a shared hosting server, preventing any single user from consuming excessive resources and crashing the server for everyone else. This ensures consistent uptime and performance.
  • Improved Security with HardenedPHP and KernelCare
    CloudLinux offers HardenedPHP, which patches old and unsupported PHP versions against known vulnerabilities, and KernelCare, which provides live kernel patching without requiring server reboots. These features significantly enhance server security posture.
  • Resource Limit Management
    Administrators can set granular resource limits (CPU, memory, I/O, number of processes, etc.) per user account using LVE Manager. This makes it easy to manage shared hosting environments and ensure fair resource distribution among tenants.
  • CageFS File System Virtualization
    CageFS creates a virtualized file system for each user, preventing them from seeing other users on the server, viewing sensitive configuration files, or exploiting server vulnerabilities. This adds an important layer of isolation and security.
  • Wide Compatibility with Hosting Panels
    CloudLinux integrates seamlessly with popular hosting control panels such as cPanel, Plesk, and DirectAdmin, making it straightforward for hosting providers to adopt without overhauling their existing infrastructure or workflows.

Possible disadvantages

  • Additional Licensing Cost
    CloudLinux requires a paid monthly or annual license on top of the base server cost. For smaller hosting providers or individual server owners, this additional expense can add up and may not always be justifiable compared to free alternatives.
  • Limited to CentOS/RHEL-Based Systems
    CloudLinux is built on top of RHEL/CentOS and does not support other Linux distributions like Ubuntu or Debian. This limits its adoption for hosting providers who prefer or already run non-RHEL-based environments.
  • Learning Curve for Configuration
    While CloudLinux provides powerful resource management tools, properly configuring LVE limits, CageFS, PHP Selector, and other features requires a solid understanding of the platform. Misconfiguration can lead to users being unnecessarily restricted or resources being poorly allocated.
  • Potential Performance Overhead
    The additional layers of virtualization, resource monitoring, and file system isolation introduced by CloudLinux can impose a slight performance overhead on the server compared to running a bare, unmodified Linux distribution without these controls.
  • Dependency on CloudLinux Ecosystem
    Adopting CloudLinux means relying on their ecosystem for kernel updates, PHP patches, and security fixes. If the company experiences delays in releasing patches or changes its pricing/licensing model, hosting providers may find themselves locked into a dependency that is difficult to migrate away from.
