Features and specs

What each product offers, as listed by its team.

Litmus 6 features
CloudLinux 5 features
  • Email Previews
    Litmus offers extensive email previews across over 90 different clients and devices, ensuring your email renders correctly for all recipients.
  • Spam Testing
    The platform includes spam testing tools to check whether an email is likely to be flagged as spam, helping to improve deliverability rates.
  • Analytics
    Detailed analytics provide insights into how recipients interact with emails, including open rates, read rates, click rates, and geographic data.
  • Integration Capabilities
    Litmus integrates with popular email service providers (ESPs) like Mailchimp, Salesforce, and HubSpot, streamlining the workflow.
  • Code Editor
    The platform includes a built-in code editor, allowing users to make real-time edits and see immediate previews.
  • Collaboration Tools
    Collaboration features enable teams to review and approve emails in one place, improving efficiency and reducing errors.

Possible disadvantages

  • Cost
    Litmus can be relatively expensive, especially for small businesses or individual users, with pricing plans starting at a higher tier.
  • Learning Curve
    The extensive feature set and advanced functionalities come with a learning curve, requiring time and effort to fully leverage the platform.
  • Occasional Rendering Issues
    Despite its capabilities, users occasionally report rendering discrepancies in email previews, requiring manual adjustments.
  • Limited A/B Testing Features
    While Litmus provides analytics, it lacks robust A/B testing functionalities compared to some other platforms.
  • Speed of Updates
    Updates and the addition of new features can sometimes be slower than user expectations, particularly in response to emerging email client updates.
  • Complexity for Basic Users
    Basic or infrequent users might find the platform overly complex for their needs, as it is designed for comprehensive email testing and analytics.
  • 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.

Why this product is good

  • Backed by an established company with a long track record in the hosting industry and responsive support

  • 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
