About FrostCam and CloudLinux

In their own words, as submitted to SaaSHub.

FrostCam
CloudLinux

FrostCam is a menu-bar app for macOS that gives you something video call apps don't: a pause button for your camera. Turning your camera off drops a black tile into the meeting grid and everyone looks up. FrostCam instead holds your video on the frame that was live at that moment - you look...

Features and specs

What each product offers, as listed by its team.

FrostCam 8 features
CloudLinux 5 features
  • Freeze Frame Feature
    Holds your video on the current frame. Press again to go live.
  • Looping Features
    Replays 3–10 seconds of you with bounce playback, so there's no visible restart seam.
  • Pricing
    Free tier, or $14.99 one-time. No subscription.
  • Network Access
    None. Ships with no network entitlement — the sandbox can't open a connection.
  • Works With
    Any macOS app with a camera picker: Zoom, Meet, Teams, FaceTime, Slack, Discord, OBS.
  • Global shortcuts
    Freeze or loop from inside your call without switching apps.
  • Platform
    macOS 13+, universal binary (Apple Silicon & Intel).
  • Distribution
    Mac App Store — Apple handles billing, refunds and Family Sharing.
  • 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 FrostCam and CloudLinux.

What makes your product unique?

FrostCam's answer

It ships with no network entitlement at all. Most webcam tools sell licences directly, which means the app needs a network connection to validate them — so the software sitting on top of your camera feed has a working socket. FrostCam is distributed through the Mac App Store, so purchases go through Apple's StoreKit outside the app, and the app itself has no network permission. The macOS sandbox cannot let it connect even if it tried. Anyone can verify this in a second: codesign -d --entitlements - /Applications/FrostCam.app

The other unusual thing is loop mode. It records 3–10 seconds of you and replays it bouncing forward and backward, so there's no visible jump where the clip restarts - which is what normally gives a looping video away.

Why should a person choose your product over its competitors?

FrostCam's answer

Price model and distribution, mainly. The closest direct competitor is $39/year. FrostCam is $14.99 once, and the free tier isn't a trial - no timer, no card, every feature works with a small watermark on the virtual camera output.

Buying through the Mac App Store means no licence key in an email, no activation server, and no account to lose. It unlocks on every Mac you own, Family Sharing works, and refunds go through Apple rather than depending on a solo developer answering support email.

One honest caveat: FrostCam has no "fake bad connection" stutter effect. App Store guideline 1.1.6 prohibits that kind of feature, and staying in the App Store was worth more to me. If the stutter effect is what you're after, a direct-download competitor is the better fit.

How would you describe the primary audience of your product?

FrostCam's answer

Mac users who spend most of the day on video calls - remote and hybrid workers in back-to-back meetings, plus teachers, students and anyone in long webinars.

The common thread is people who are on camera for hours and occasionally need ten seconds off it without making that everyone's business: a sneeze, a knock at the door, a glance at a phone. Not people trying to skip meetings entirely.

What's the story behind your product?

FrostCam's answer

I'm a solo developer in Hungary. I built it because of a specific small annoyance: in a long call you sometimes need a few seconds away, but switching the camera off drops a black tile into the grid and everyone looks up. The workaround shouldn't be more disruptive than the interruption.

A frozen frame keeps the rhythm of the call - it reads as "got very still" rather than "left". The existing options were subscriptions, which felt steep for what is fundamentally a pause button, so I built one and put it on the App Store for a one-time price.

Which are the primary technologies used for building your product?

FrostCam's answer

Swift and SwiftUI throughout, with no third-party dependencies.

The virtual camera is a CoreMediaIO Camera Extension - Apple's modern replacement for DAL plugins, which were disabled in macOS 14.1. Webcam capture is AVFoundation, frames pass between the app and the extension through a shared IOSurface for zero-copy transfer, and purchases use StoreKit 2. Universal binary for Apple Silicon and Intel.
