WP Rocket – Is it worth buying?

Even though it’s all premium, the plugin is totally worth the price.

For instance, if you want the same functionalities as WP Rocket using free options, you have to install a cache enabler for caching, autoptimize for minification, WP-optimize for data cleaning, etc. This means that you have to spend more time configuring them and make sure they work properly in the present and future.

With WP Rocket, you are paying for convenience. You can install it and not worry about maintaining several performance plugins. Plus, you get premium support.

So, if you want to optimize your WordPress website and enhance its performance, we’d recommend WP Rocket.
