Features and specs

What each product offers, as listed by its team.

ProperCalc 5 features
CloudLinux 5 features
  • Clean and intuitive interface
    ProperCalc's mortgage calculator features a straightforward, uncluttered design that makes it easy for users to input their loan details and quickly understand the results without being overwhelmed by unnecessary complexity.
  • Detailed amortization schedule
    The calculator provides a comprehensive amortization schedule that breaks down each payment into principal and interest components, allowing users to see exactly how their mortgage balance decreases over time.
  • Multiple language support
    The app offers multilingual support (as indicated by the /en/ URL path), making it accessible to a broader international audience and more inclusive for non-English speakers.
  • Free to use
    ProperCalc appears to be a free web-based tool that doesn't require registration or payment to access its core mortgage calculation features, making it accessible to anyone with an internet browser.
  • Visual payment breakdown
    The calculator includes visual elements such as charts and graphs that help users quickly grasp the proportion of interest versus principal in their mortgage payments, making complex financial data easier to digest.

Possible disadvantages

  • Limited advanced features
    Compared to more robust mortgage calculators, ProperCalc may lack advanced options such as bi-weekly payment calculations, PMI estimation, property tax and insurance inclusion, or the ability to factor in extra payments for payoff scenarios.
  • No account or save functionality
    Users may not be able to create an account or save their calculations for future reference, meaning they would need to re-enter their data each time they visit the site.
  • Limited brand recognition
    ProperCalc is a lesser-known tool compared to established mortgage calculators from major financial websites like Bankrate or NerdWallet, which may make some users hesitant to trust its accuracy or reliability.
  • No integration with lenders
    The calculator doesn't appear to offer direct integration with mortgage lenders or rate comparison tools, so users can't seamlessly transition from calculating payments to shopping for actual mortgage offers.
  • Limited educational content
    Unlike larger financial platforms, ProperCalc may not provide extensive educational resources, guides, or articles alongside its calculator to help users better understand mortgage concepts and make more informed decisions.
  • 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.
