About serrv and CloudLinux

In their own words, as submitted to SaaSHub.

serrv
CloudLinux

serrv is a native macOS app for previewing static websites locally on a real web server — at a proper address like https://portfolio.local/, with a trusted certificate and the secure lock icon, exactly as the site will look once published. Opening a finished site as a file (file://) breaks things...

Features and specs

What each product offers, as listed by its team.

serrv 3 features
CloudLinux 5 features
  • Real local HTTPS
    Serves each site at a trusted https://….local address with the secure lock icon
  • Static-site focused
    HTML, CSS, JavaScript — no PHP, Python or databases
  • Custom .local domains
    Stable names like portfolio.local, no port numbers
  • 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.

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 serrv and CloudLinux.

What makes your product unique?

serrv's answer

serrv previews static websites on a real local web server at a trusted address like https://portfolio.local/ — with a valid certificate and the secure lock icon, in every browser including Firefox. Unlike opening files directly (file://) or a plain dev server on http://localhost:port, serrv reproduces a real production origin, so root-relative paths, clean URLs, fetch()/ES modules, service workers and secure-context APIs all behave exactly as they will once published.

Why should a person choose your product over its competitors?

serrv's answer

Most local dev tools (MAMP, Laravel Herd, Valet) are built around PHP and databases. serrv is deliberately static-only and focuses on one thing done well: a real, trusted HTTPS address for your finished site, with zero setup. No port numbers, no self-signed certificate warnings, no Firefox workaround, and all your sites stay available at once. It complements your SSG dev server rather than replacing it — keep astro dev or eleventy --serve for editing, use serrv as the final check on a real address.

How would you describe the primary audience of your product?

serrv's answer

Developers and designers who build static websites — by hand, with static site generators like Eleventy, Astro or Hugo, or with AI tools. Anyone who wants to verify a finished build exactly as it will look live before publishing, especially those testing HTTPS-only behavior like service workers or secure-context APIs.

What's the story behind your product?

serrv's answer

serrv comes from MAMP GmbH, long known for local development environments on the Mac. As static sites and static site generators became mainstream, a recurring problem stood out: a finished static site opens fine on a live server, but double-clicking it locally quietly breaks — missing assets, dead links, no lock icon, disabled secure-context features. serrv was built to close that gap with a deliberately simple, static-focused Mac app.

Who are some of the biggest customers of your product?

serrv's answer

serrv is newly launched; it's used by independent developers, designers and studios building static sites on macOS.

Which are the primary technologies used for building your product?

serrv's answer

serrv is a native macOS app (macOS 15+). The local web server is powered by Caddy, and file transfer in serrv max uses rclone. It runs entirely on your Mac — no cloud and no account required.
