Features and specs

What each product offers, as listed by its team.

Polypane 8 features
CloudLinux 5 features
  • Multi-View Testing
    Polypane allows developers to view and test their website in multiple screen sizes simultaneously, making responsive design testing more efficient.
  • Live Reloading
    The application supports live reloading, which means any changes made to the code are instantly reflected in the preview panes without needing to refresh manually.
  • Developer Tools Integration
    Polypane integrates seamlessly with common developer tools and frameworks, enhancing the workflow for developers who use tools like React, Vue, and Angular.
  • Accessibility Checks
    Built-in accessibility tools help ensure that web pages comply with accessibility standards, making it easier to identify and fix issues.
  • Performance Insights
    The software provides performance metrics and recommendations, aiding developers in optimizing load times and overall performance.
  • Collaboration Features
    Polypane includes features designed for team collaboration, such as the ability to share previews and feedback with team members.
  • Dark Mode
    A dark mode option is available, offering a more comfortable viewing experience for developers who prefer it or work in low-light conditions.
  • Customizable Layouts
    Users can customize the layout of the panes to better suit their workflow, offering a flexible user experience.
  • 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.
