# What caching plugins can I use?

The Dollie platform tries to auto-detect the most popular WP caching plugins and auto implements container-level caching before WordPress is even loaded. This solution gives you the freedom to choose a caching plugin that works best for you, whilst still getting all the benefits of NGINX caching. Once a page is cached it is served directly through NGINX completely bypassing PHP and MySQL and thus resulting in near instant load times.

  

## Do I need to install a caching plugin?

No. By default your wordpress sites will include the free Powered Cache plugin.

  

## Can I install an alternative caching plugin?

 Yes, the following caching plugins are supported:

*   WP Rocket
*   W3 Total Cache
*   WP Super Cache
*   Cache Enabler
*   Switch Performance
*   WP Fastest Cache
*   Litespeed Cache
*   Hyper Cache
*   CometCache
*   NGINX Helper (FastCGI Cache)

  

## What about Object Caching?

Yes, this is supported via all Redis Object Cache plugins/dropins.
