Features and specs

What each product offers, as listed by its team.

calculate.at 5 features
CloudLinux 5 features
  • Free to use
    The website appears to offer calculation tools without requiring payment, making it accessible to users who need quick calculations without a subscription cost.
  • Simple interface
    Calculator websites like this typically feature straightforward, uncluttered interfaces that allow users to input numbers and get results quickly without a steep learning curve.
  • Convenient online access
    Being web-based, it can be accessed from any device with an internet connection and a browser, without needing to download or install any software.
  • No registration required
    Many online calculator tools allow immediate use without requiring users to create an account, sign up, or provide personal information.
  • Austrian domain relevance
    The .at domain suggests it may cater to Austrian or German-speaking users, potentially offering localized units, currency, or tax calculations relevant to that region.

Possible disadvantages

  • Limited information available
    Without extensive documentation or reviews, it can be difficult to verify the full range of features, accuracy, and reliability of the calculations provided by the site.
  • Possible advertising
    Free calculator websites often rely on advertisements for revenue, which can clutter the interface and potentially slow down page loading times or distract users.
  • Uncertain data privacy practices
    As with many smaller websites, there may be limited transparency about how user input data is stored, processed, or potentially shared with third parties.
  • Dependence on internet connectivity
    Since it is a web-based tool, users need a stable internet connection to access and use the calculator, unlike offline calculator applications.
  • Potential lack of advanced features
    Basic online calculators may not offer the same depth of functionality as specialized software or apps designed for complex mathematical, financial, or scientific calculations.
  • 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

  • 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

  • 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

  • Why I never built a backend for a site with 290+ calculators
    I run calculate.at, a free site with 290+ online calculators — mortgage payments, BMI, unit conversions, percentages, that kind of thing. No account system, no analytics pixels chasing you around, no backend at all. Every calculation... - Source: dev.to / 3 months ago
