Features and specs

What each product offers, as listed by its team.

CloudLinux 5 features
Rezup.ai 12 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.

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 Rezup.ai.

What makes your product unique?

Rezup.ai's answer:

Customers answer by voice instead of filling in a form. They scan a QR code or open a link, tap record and talk in their own language, with no app or account. Rezup transcribes and translates every answer into the owner's language, so a café in Lisbon can read what a Japanese tourist said. AI then groups answers into themes and flags the ones that need a reply.

Why should a person choose your product over its competitors?

Rezup.ai's answer:

Form tools like Typeform or Google Forms get short answers and star ratings; people skip long forms. A 30-second voice message carries far more detail, and Rezup makes it readable: every answer is transcribed and translated automatically. Unlike video tools such as VideoAsk, customers don't need to show their face, and the owner reads text instead of watching clips. Data is hosted in the EU, responses are never used to train AI, and there is a free plan with 25 responses and 14 days of Growth features.

How would you describe the primary audience of your product?

Rezup.ai's answer:

Owners and managers of small and mid-sized businesses that serve customers in person: restaurants, cafés, hotels, clinics, salons and shops, especially those with international guests. Also online businesses such as course creators, SaaS and e-commerce teams that want real feedback and voice testimonials instead of survey scores.

What's the story behind your product?

Rezup.ai's answer:

Rezup started with BlaBlaScribe AI, my transcription product. I wanted to know what to improve, but star ratings told me nothing: a "4 out of 5" never says what's wrong or what to fix. I needed users' own words, and typing a long answer is a chore most people skip. Talking for 30 seconds is easy. We already had speech recognition running on our own servers for BlaBlaScribe, so I built the simplest possible path: one question, a record button, and every answer arrives transcribed and translated into my language. It worked so well that it became its own product. Now Rezup does the same for any business that wants real feedback instead of ratings.

Which are the primary technologies used for building your product?

Rezup.ai's answer:

Laravel (PHP), Vue.js with Inertia, MySQL, self-hosted WhisperX speech recognition on our own GPU servers, Google Gemini for translation and AI analysis, Stripe for payments, Brevo for email, hosted on Hetzner in the EU behind Cloudflare.
