Features and specs

What each product offers, as listed by its team.

Open Shell 5 features
CloudLinux 5 features
  • Customization
    Open Shell provides extensive customization options, allowing users to modify the Start menu to fit their preferences, from design to functionality.
  • Familiar Interface
    It offers a classic start menu which is familiar to users of older Windows versions, making it easier for them to navigate.
  • Open Source
    Being an open-source project, it allows for community contributions, making it more transparent and potentially more secure.
  • No Cost
    Open Shell is free to use, providing a cost-effective solution for users who want a different Start menu experience without paying for software.
  • Regular Updates
    The project is fairly well-maintained, receiving updates that add new features and fix potential issues, improving user experience over time.

Possible disadvantages

  • Compatibility Issues
    There could be compatibility problems with certain Windows updates or third-party applications, requiring troubleshooting and fixes.
  • Learning Curve
    While it offers many customization options, new users might find the settings and customization process overwhelming and confusing initially.
  • Community Support
    As an open-source project, it relies heavily on community support rather than professional customer service, which can be a drawback for users needing prompt assistance.
  • Resource Usage
    Though generally lightweight, Open Shell can consume additional system resources, which might be impactful on less powerful machines.
  • 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.

CloudLinux

Overall verdict

  • Open Shell is considered a good tool for those who desire a more traditional Start Menu experience on modern Windows versions. It is reliable, versatile, and generally well-received by the community for resurrecting the familiar interface from previous Windows iterations.

Why this product is good

  • Open Shell (formerly known as Classic Shell) is appreciated for its ability to bring back the classic Start Menu functionality to Windows, particularly for users who prefer the interface design and usability of older versions of Windows. It provides a customizable menu, various skins, and additional enhancements for the Start Button, File Explorer, and Internet Explorer. The software is lightweight, free, and open source, allowing for a high degree of personalization and adaptability.

  • Users seeking a highly customizable and lightweight menu solution.
  • Technical users who appreciate open-source software and want to tweak their system appearance and functionality.
  • Anyone upgrading from older Windows versions who wants to maintain a consistent user interface experience.

Overall verdict

  • CloudLinux is a well-regarded, mature Linux OS distribution and toolset specifically designed for shared hosting and multi-tenant server environments, offering strong isolation, resource management, and security features that make it a solid choice for hosting providers.

Why this product is good

  • Provides LVE (Lightweight Virtual Environment) technology for per-tenant resource isolation, preventing 'bad neighbor' effects on shared servers
  • Enhances server stability and security by isolating users so that one account's issues (crashes, resource spikes) don't affect others
  • Offers extended lifecycle support (longer than standard CentOS/RHEL support windows), which is valuable for legacy systems
  • Includes tools like CloudLinux OS Shield, Imunify360 integration, and hardened kernel options for improved security
  • Compatible with popular control panels like cPanel and Plesk, making it easy to integrate into existing hosting stacks
  • Backed by an established company with a long track record in the hosting industry and responsive support
  • Offers granular control over CPU, memory, I/O, and other resources per user account
  • Provides PHP Selector and multiple PHP version support, useful for hosting providers serving diverse client needs

Recommended for

  • Web hosting companies running shared or reseller hosting environments
  • Hosting providers needing to isolate customer accounts on the same physical server
  • Businesses requiring extended OS support lifecycles beyond standard RHEL/CentOS EOL dates
  • Enterprises using cPanel or Plesk that want tighter security and resource control
  • Hosting companies looking to reduce support tickets caused by noisy-neighbor resource contention
  • IT teams managing multi-tenant infrastructure who need governance and monitoring tools built into the OS layer
