Features and specs

What each product offers, as listed by its team.

CloudLinux 5 features
SideNote Pro 8 features
  • 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.
  • Native Windows assistant
    Built for Windows 11 with an always-on-top, dockable desktop interface
  • Multiple AI providers
    Supports OpenAI, Anthropic, Gemini, DeepSeek and custom OpenAI-compatible endpoints
  • Local AI models
    Connects directly to Ollama and LM Studio running on the PC
  • Selected-text actions
    Summarize, rewrite, explain, translate or ask AI using global keyboard shortcuts
  • Documents & images
    Supports screenshots, images, PDF, Word, text and Markdown files
  • Local folder context
    Index selected folders locally and use relevant file content as AI context
  • Local-first privacy
    Conversation history, settings and folder indexes remain on the Windows PC
  • Docked drawer mode
    Stays beside your work and retracts into a compact right-edge handle when not needed

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 CloudLinux and SideNote Pro.

What makes your product unique?

SideNote Pro's answer:

SideNote Pro is designed as a native Windows companion rather than another AI destination. It can stay beside the application you are working in, remain always on top, dock to the edge of the desktop, and retract into a small handle when not needed. It also uses a bring-your-own-provider model, supporting both cloud AI services and local models through Ollama or LM Studio.

Why should a person choose your product over its competitors?

SideNote Pro's answer:

SideNote Pro is aimed at users who want AI available inside their normal Windows workflow without constantly switching to a browser or separate workspace. It combines a native Windows interface with global shortcuts, selected-text actions, documents, images, local folder context, multiple AI providers, and local model support. Users choose their own AI provider instead of being tied to a bundled subscription.

How would you describe the primary audience of your product?

SideNote Pro's answer:

Windows 11 users who regularly use AI while working in applications such as browsers, Office tools, creative software, development environments, and other desktop applications. It is particularly suited to people who want quick access to cloud or local AI models without interrupting their existing workflow.

What's the story behind your product?

SideNote Pro's answer:

SideNote Pro started from a simple frustration: using AI for small tasks often meant leaving the application being worked in, finding the browser, switching to an AI tab, asking the question, and then returning to the original task. The goal became to keep the assistant beside the work instead. What began as a compact chat window gradually expanded with selected-text actions, documents, images, local folder context, multiple providers, local AI models, and a dockable Windows interface.

Which are the primary technologies used for building your product?

SideNote Pro's answer:

C#, .NET 10, WinUI 3, Windows App SDK, and OpenAI-compatible APIs. SideNote Pro is a native Windows 11 x64 desktop application.
