About CloudLinux and Dubsend

In their own words, as submitted to SaaSHub.

CloudLinux

Dubsend

No description of CloudLinux yet.

CloudLinux 5 features

Dubsend 3 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.

Questions & Answers

As answered by people managing CloudLinux and Dubsend.

How would you describe the primary audience of your product?

Dubsend's answer:

Independent record labels, artists who release their own music and promo agencies that send unreleased music to DJs, radio and press before release. DJs and radio hosts use Dubsend to receive promos and keep them in one free inbox.

What makes your product unique?

Dubsend's answer:

Dubsend measures listening time per person and per track, so a label can see who actually played the music. Labels can require feedback before a download, and opens from email privacy tools are counted separately so the open numbers stay honest. Every download is tagged with the recipient's name.

Which are the primary technologies used for building your product?

Dubsend's answer:

Next.js and React, hosted on Cloudflare Workers, with a Postgres database on Supabase, Amazon SES for email delivery and Stripe for billing.

Why should a person choose your product over its competitors?

Dubsend's answer:

There is a free plan with no card needed, and paid plans start at £12 a month. Each promo page carries the label's own logo and colours, and recipients need no account or app. Reports can be shared with the artist as a link or a PDF, and DJs can keep every Dubsend promo in one free inbox.

What's the story behind your product?

Dubsend's answer:

We run music releases ourselves and wanted a promo tool that shows who actually listened, keeps each label's own branding and stays affordable for small labels. We built Dubsend for that and opened it to everyone in October 2026.
