Features and specs

What each product offers, as listed by its team.

Screaming Frog 5 features
CloudLinux 5 features
  • Comprehensive Website Audits
    Screaming Frog can crawl websites and provide detailed insights including broken links, duplicate content, and redirect issues, offering a thorough audit of site health.
  • Customizable Crawls
    Users can tailor the crawl settings to meet specific needs, such as including/excluding certain parts of a site, or focusing on specific parameters like HTML, CSS, or JavaScript.
  • Integration with Analytics
    The tool seamlessly integrates with Google Analytics and Google Search Console, allowing for enriched data analysis and reporting.
  • In-Depth SEO Analysis
    Screaming Frog provides extensive SEO insights, including metadata analysis, site structure review, and page depth insights, helping improve on-page SEO.
  • Exportable Data
    Users can easily export the collected data into different formats such as CSV, Excel, or Google Sheets for further analysis and reporting.

Possible disadvantages

  • Learning Curve
    Due to its extensive features and settings, new users may find Screaming Frog difficult to navigate and require some time to fully master.
  • Resource Intensive
    Crawling large websites can be resource-intensive, potentially slowing down your machine or requiring substantial computing power.
  • Premium Cost
    While there is a free version, the full feature set of Screaming Frog is locked behind a paid subscription, which might be costly for small businesses or individual users.
  • JavaScript Rendering
    Despite improvements, Screaming Frog's ability to render and crawl JavaScript-heavy sites is still not as robust as some specialized tools.
  • User Interface
    The interface can feel cluttered and overwhelming to some users, making it less user-friendly compared to some other SEO tools with more modern designs.
  • 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.
