About AspectCalc and CloudLinux

In their own words, as submitted to SaaSHub.

AspectCalc
CloudLinux

AspectCalc turns any width and height into a simplified ratio, resizes to a target ratio, and shows a live visual preview as you type — so you see the actual shape before you commit to it, not just the numbers. How it works Type in a resolution (e.g. 1920×1080) and it shows the reduced ratio...

Features and specs

What each product offers, as listed by its team.

AspectCalc 6 features
CloudLinux 5 features
  • Ratio Calculator
    Converts any width and height into a simplified aspect ratio and decimal value
  • Resize by Ratio
    Calculates the missing width or height for any target aspect ratio
  • Live Visual Preview
    Shows the rectangle shape update in real time as you type
  • Closest Standard Ratio Match
    Flags how close a non-standard resolution is to the nearest common ratio like 16:9 or 4:3
  • CSS Export
    One-click copy of the CSS aspect-ratio property for the calculated ratio
  • No Sign-Up Required
    Fully usable without creating an account, runs entirely in the browser
  • 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.

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

Questions & Answers

As answered by people managing AspectCalc and CloudLinux.

Which are the primary technologies used for building your product?

AspectCalc's answer

HTML, CSS, JavaScript

Why should a person choose your product over its competitors?

AspectCalc's answer

Most aspect ratio calculators only do simple division and stop there. AspectCalc adds a live preview so you can visually confirm a crop or resize before committing, a "closest standard ratio" check for imprecise resolutions, and a one-click CSS export — all with no sign-up and no ads.

What makes your product unique?

AspectCalc's answer

It handles both directions of the aspect ratio problem in one tool — calculating the ratio from a given size, and resizing to a target ratio — with a live visual preview that shows the actual shape as you type, not just numbers. It also flags how close a non-standard resolution is to the nearest common ratio (useful for catching things like a "16:9" screen that's actually slightly off), and lets you copy the CSS aspect-ratio property in one click.

How would you describe the primary audience of your product?

AspectCalc's answer

Content creators, video editors and social media managers who need to resize content across platforms with different aspect ratios (Instagram, TikTok, YouTube), along with designers and front-end developers who need exact ratio math for layouts and CSS.

What's the story behind your product?

AspectCalc's answer

Built out of a recurring personal annoyance — manually calculating aspect ratios every time a video or image export needed to fit a different platform's required shape. Rather than doing the division by hand each time, AspectCalc turned that into a tool that handles both directions of the calculation with a live preview.
