Features and specs

What each product offers, as listed by its team.

CloudLinux 5 features

Trailback 13 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 Trailback.

Why should a person choose your product over its competitors?

Trailback's answer:

Rewind has stopped recording, and Microsoft Recall only runs on Copilot+ PCs. Trailback works on any Mac (macOS 13+) or Windows 10/11 PC, fully offline, for a one-time price instead of a subscription.

Beyond search, you also get Quick Search from any app (with drag and drop), a timeline to go back and reopen past work, automatic Collections, Tidy for messy file names, and offline PDF and image tools.

What makes your product unique?

Trailback's answer:

Trailback remembers what you did on your computer: websites you visit, files you open, screenshots you take and text you copy. You find any of it by describing it in your own words, like "the invoice from last month".

It does all of this 100% offline. Nothing is uploaded, there's no account, and your data is stored encrypted on your own computer. And it works on both Mac and Windows.

How would you describe the primary audience of your product?

Trailback's answer:

Founders, freelancers, knowledge workers, students and researchers. Anyone who works across lots of files, browser tabs and screenshots and keeps losing things they know they've seen.

It's also for people who care about privacy and don't want an app uploading their activity to the cloud.

What's the story behind your product?

Trailback's answer:

I'm Pavan, a solo founder from Hyderabad. I kept losing things I knew I'd seen: a PDF from last week, a page I read, a screenshot with a number in it. I never remember file names. I remember what the thing was about.

The tools that solved this either sent my data to the cloud or only worked on certain hardware. So I built Trailback: a memory for your computer that stays on your computer.
