I admire anything extensible in this life, hence I’ve been always a fan of extensible WordPress plugins, those plugins that you can actually talk to them if you know how to speak their language.
So what’s an extensible plugin means?
In software engineering, extensibility (not to be confused with forward compatibility) is a system design principle where the implementation takes future growth.
An extensible WordPress plugin is a plugin that can extended by another plugin, or what’s commonly known as an add-on. So, for example, if you have a plugin A, you can extend its functionality by installing another plugin called B on your WordPress site.
Example of Extensible WordPress Plugins
Here I am going to share with you some popular and upcoming examples of extensible WordPress plugins that you may find useful for your website. I personally use a few of them.
My first example is the amazing Gravity Forms plugin. It’s by far one of my most recommended plugin to create and manage web forms in WordPress. However, that’s not the only thing this plugin can do!
Gravity Forms is a truly extensible plugin, you can make it do great things rather than only create a web form by the help of add-ons. There are many add-ones developed for the Gravity Forms plugin, I my self consider a few of these add-ons essential for my WordPress sites, and recommend them to every blogger and internet marketer, for example the PayPal, Aweber and MailChimp addons.
Another way to extend the plugin functionality is to use the Gravity Forms API, which provide you with a future-proof way to access some of the common core functionality in the plugin, however you may need some coding experience to be able to get the most out of it.
Firstly, I must mention that Thirsty Affiliates plugin wasn’t extensible back in time when it was first released. Only a few months ago; Thirsty Affiliates plugin got a new plan. It was released for free at the WordPress plugin directory, and now it’s extendable via a number of Pro Add-ons that can be purchased from its website.
Some of my favorites ThirstyAffiliates add-ons are the Autolinker and Stats.
I do actually use it on almost all my WordPress sites, and I highly recommended it for affiliate marketers.
Restrict Content Pro
Restrict Content Pro is a complete membership and premium content manager plugin for WordPress.
I never had a chance to use or try this plugin, but I’ve came across a couple of other plugins from Pippin -the author- who has really great coding skills, you can clearly see through his clean code and its powerful performance. His old but gold post about extensible code helped me a lot in understanding how to actually make my coming plugin plugin extensible.
There are some really cool add-ons for the Restrict Content Pro!
Check out the Restrict Content Pro plugin.
Visual Composer: Page Builder for WordPress
This is by far one of the best page builders plugin I’ve ever used!
I’ve seen this plugin exploding, really! Many developers started to release their own add-ons that extends the functionality of the visual composer plugin and adds more elements to it.
I hope you found this post useful!
