Features and specs

What each product offers, as listed by its team.

Online Ruler pro 5 features
CloudLinux 5 features
  • No Installation Required
    Online Ruler Pro works directly in the browser, so users don't need to download or install any software to measure objects on their screen.
  • Free to Use
    The tool is available at no cost, making it accessible to anyone who needs a quick digital ruler for on-screen measurements.
  • Easy to Use
    The interface is straightforward and intuitive, allowing users to quickly measure items by placing them against the screen without a steep learning curve.
  • Multiple Unit Support
    Online Ruler Pro supports various measurement units such as inches and centimeters, giving users flexibility depending on their measurement needs.
  • Accessible Across Devices
    As a web-based tool, it can be accessed from different devices including desktops, laptops, and tablets, as long as there is a browser available.

Possible disadvantages

  • Accuracy Depends on Screen Calibration
    The accuracy of measurements relies heavily on correct screen calibration. If the screen DPI or resolution settings are not properly configured, measurements can be significantly off.
  • Limited to On-Screen Measurements
    The ruler can only measure objects that can be placed against or compared to the screen, which limits its practical applications compared to a physical ruler.
  • Screen Size Limitations
    The maximum measurable length is constrained by the physical size of the user's screen, making it impractical for measuring larger objects.
  • Requires Internet Connection
    Since it is a web-based tool, users need an active internet connection to access and use the ruler, which may not always be available.
  • Not Suitable for Precision Work
    Due to inherent limitations of screen-based measurement, the tool is not reliable enough for professional or precision tasks where exact measurements are critical.
  • 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.

Analysis

An editorial look at what each product does well and who it suits.

Online Ruler pro
CloudLinux

Overall verdict

  • Online Ruler Pro appears to be a simple browser-based virtual ruler tool for quick, rough on-screen measurements. It can be handy for basic tasks but is not a substitute for a physical ruler when precision matters, since on-screen measurement accuracy depends on your display's resolution, zoom level, and calibration.

Why this product is good

  • Free and instantly accessible without downloads or installations
  • Convenient for quick estimates when a physical ruler isn't available
  • Simple, no-frills interface for basic measurement needs
  • Useful for cross-checking rough dimensions of digital images or on-screen objects

Recommended for

  • Users needing a quick, rough measurement without a physical ruler on hand
  • Students or hobbyists checking approximate sizes of on-screen items
  • People who don't require high-precision measurements
  • Casual, one-off use cases rather than professional or technical measurement tasks

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
