  • Geography & device
    Country-level location and device type per view. IP is hashed for lookup, then discarded
  • Quick share
    Create a tracked link in one click, without configuring any gates
  • 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.

PDFTrackr's answer

Next.js, TypeScript, PostgreSQL, React, Docker, DigitalOcean, Cloudflare

What makes your product unique?

PDFTrackr's answer

It's the only PDF tracker that shows you which views were real. Bots and email scanners are filtered out of your counts automatically, and the dashboard shows exactly what it removed. Then Signals tell you who came back and who's worth a follow-up, with a per-recipient verdict on whether a specific person read it, so you act on real buyers instead of inflated numbers.

Why should a person choose your product over its competitors?

PDFTrackr's answer

Most trackers count every open, including bots and email scanners that never read a word. PDFTrackr filters them out and shows its work, so the numbers are real. Then Signals do the analysis for you: who's genuinely engaged, who's worth a call now, plus a per-recipient verdict and real-time alerts with emailed Reading Reports. Full page-by-page analytics are free with a 12-month history and virus scanning, no credit card; Pro is $9/month or $84/year.

How would you describe the primary audience of your product?

PDFTrackr's answer

What's the story behind your product?

PDFTrackr's answer

Built to answer the question every sender has: did they actually read it, and when should I follow up? Instead of a vanity view counter that inflates numbers with bots, PDFTrackr filters out the noise and turns real reads into a shortlist of who's worth a call.
