Features and specs

What each product offers, as listed by its team.

SelfDB 5 features
CloudLinux 5 features
  • Self-hosted and open-source
    SelfDB is designed to be self-hosted, giving users full control over their data and infrastructure without relying on third-party cloud services, which enhances privacy and data sovereignty.
  • Multiple services in one platform
    SelfDB combines several backend services such as database, authentication, storage, and real-time features into a single self-hosted solution, reducing the need for multiple separate tools.
  • Supabase-like alternative
    It provides a self-hosted alternative to popular Backend-as-a-Service platforms like Supabase and Firebase, making it appealing for developers who want similar functionality without vendor lock-in.
  • Simple deployment
    SelfDB aims to provide straightforward deployment options, often using Docker or similar containerization, making it relatively easy to get started with a self-hosted backend solution.
  • Cost-effective
    Being open-source and self-hosted, SelfDB can be significantly more cost-effective than managed BaaS platforms, especially for projects that scale, as you only pay for your own infrastructure costs.

Possible disadvantages

  • Limited community and ecosystem
    As a relatively niche and lesser-known project, SelfDB has a smaller community compared to established alternatives like Supabase, which means fewer tutorials, plugins, and community-driven support resources.
  • Self-hosting maintenance burden
    Users are responsible for managing, updating, securing, and backing up their own infrastructure, which requires DevOps knowledge and ongoing time investment that managed services handle automatically.
  • Less mature and feature-complete
    Compared to well-funded and widely adopted platforms, SelfDB may lack some advanced features, polished client libraries, or integrations that more established BaaS products offer.
  • Limited documentation
    Smaller projects often have less comprehensive or less frequently updated documentation, which can make onboarding, troubleshooting, and advanced configuration more challenging for new users.
  • Scalability concerns
    Self-hosted solutions like SelfDB may require significant manual effort and expertise to scale effectively under high traffic or large data loads, unlike managed services that handle scaling automatically.
  • 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.

  • Open-source and self-hostable, giving you complete ownership and control over your data
  • Provides an integrated backend stack including database, authentication, storage, and APIs out of the box
  • Eliminates vendor lock-in and can reduce ongoing costs compared to managed cloud BaaS providers
  • Privacy-friendly since data stays on your own infrastructure, helping with compliance requirements
  • Developer-friendly with instant APIs and tooling that speed up application development

Recommended for

  • Developers and startups wanting a self-hosted alternative to Firebase or Supabase
  • Teams with strict data privacy, security, or compliance requirements
  • Projects that need to avoid vendor lock-in and retain full infrastructure control
  • Cost-conscious builders looking to minimize managed service fees

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

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
