The cPanel and DirectAdmin Varnish Plugins

The cPanel Varnish Plugin is a feature-rich software product built by UNIXy, a fully managed server company, that enables owners of cPanel WHM servers to install, control, and manage Varnish Cache from the comfort of their cPanel WHM interface. The plugin includes several features that go beyond the installation of Varnish. We have engineered the most stable, reliable, and fastest VCL in the market. We have perfected the plugin and improved it to include features that would otherwise cost thousands of dollars to implement. Your websites load at record speeds while maintaining compatibility with the cPanel technosystem including EasyApache, Apache, an PHP modules and extensions.

Varnish Cache Made Friendly

The plugin takes less than a minute to install and run. The Varnish Configuration Language comes fully enabled and compatible with your scripts and software. Streamline your Varnish deployments and management.

Compatibility and Performance

We have engineered the plugin so Apache and PHP continue to run unaffected. Your software is guaranteed to be compatible with the VCL logic. Best of all you gain a whole new world of performance, stability, and features.

SSL/TLS Caching

The plugin is able to cache SSL/TLS traffic by SSL-terminating traffic on the fly and routing it through Varnish. This is in addition to improved TLS handshake and session caching.

WordPress, Magento, and Drupal Add-ons

Starting from plugin version 2.2.0, we have released script-specific add-ons for WordPress, Magento, and Drupal. This means Varnish delivers even greater performance for these scripts while maintaining full compatibility. Read more.

WordPress and Drupal Warp

Warp is an add-on solution targeted at Wordpress and Drupal powered Web sites. It's a one-click solution for end users who simply want their websites to load faster than the rest of the Web.

Enhanced Security Rules

We have gone above and beyond to enhance the plugin with VCL native Modsecurity rules that will protect your server from SQL injection, hacking attempts, and malicious activity. Varnish's multi-threading architecture makes it tenacious and a strong deterant of Denial of Service attacks.

Feature Rich

The plugin has matured to include over 20 features ranging from convenience and performance to security. With a few mouse clicks, you now have unprecedented access and control of performance, security, and stability.

End User Features

Your end users enjoy the best experience. They have access to cPanel controls that gives them granular control over Varnish caching, down to the subdomain level. They can turn on/off caching, adjust file / page caching, and purge the cache all from a simple screen without needing to enter a single support request.

The below benchmark results were obtained by putting both Litespeed and Varnish+Apache under the same stress conditions, resource availability, and network conditions. Needless to say, the Apache / Varnish configuration is miles ahead of Litespeed. It serves requests faster AND uses much less memory. Details of the benchmark and conditions are available here: http://www.unixy.net/apache-vs-litespeed/

Apache Litespeed Varnish Benchmark

Litespeed Tech has been running a desperate online campaign to undermine the performance of Varnish Cache even though independent benchmarks of Varnish+Apache vs Litespeed have shown that Varnish/Apache is 500 req/s FASTER than Litespeed. Also, several independent testers have confirmed that their Web sites "feel" faster with Varnish than when running Litespeed (even when Litespeed Cache is enabled).


The UNIXY cPanel plugin comes with a Web interface to manage Varnish via cPanel WHM. The cPanel app takes the complexity out of Varnish in a consolidated one-stop interface. The script allows you to uninstall Varnish, modify Varnish settings, lookup caching stats, refresh the Varnish cache, restart Varnish, and much more!

cPanel Varnish Script

The script installation is straightforward and trouble free. It takes less than one minute to have Varnish up and running!
