When it comes to building a WordPress theme, there are three ways you can go with:

  • Converting a PSD file to a WordPress theme aka PSD to WordPress conversion
  • Beginning with the rudimentary code and develop the theme around it
  • Using a base/starter WordPress theme or framework

The last one is probably the simplest, quickest, and most efficient way to build a custom WordPress theme. However, with many theme frameworks available, choosing the right one can sometimes be a daunting task. To make the selection process easier, we have researched and gathered the best free WordPress theme frameworks. Let’s start by understanding what exactly a WordPress theme framework is.


What Is a WordPress Theme Framework?

According to WordPress itself, the term ‘theme framework’ indicates two meanings:

  • A “drop-in” code library designed to speed up the theme development process. For instance, Hybrid Core, Vafpress, and Gantry.
  • A stand-alone “base/starter” theme intended to be served as a parent theme or forked into a different theme. Examples include
    Underscores and Themify Basic.

In a nutshell, a WordPress theme framework is a set of functions, features, and standards that provide developers a flexible foundation for accelerating the theme development process. All you need to create a child theme to house your customizations and leave everything else to the framework.

The Benefits of Using a WordPress theme Framework

Using WordPress theme frameworks benefit you in several ways, including:

#Ease of Development:

Frameworks are created to aid theme development. No matter if you’re a WordPress beginner or expert, building a custom WordPress theme through a framework is super easy.

#Saves Time:

A WordPress theme framework speeds up the development process manifold. As they come packed with base code, you don’t need to reinvent the wheel. Just pick the framework of your choice, and you’re good to go!

#More Efficient Upgrades:

As WordPress theme frameworks rely on child themes, they make the upgrading/updating process a lot easier. You only need to update the framework without making any modifications to the child theme. Thus, you never lose your WordPress theme customizations!

#Quality of the Code:

Theme frameworks follow W3C standards strictly. Multiple developers review them, so they follow WordPress development best practices. Consequently, their code is clean and well-documented.

#Enhanced Functionality:

WordPress theme frameworks have built-in widgets and offer functionalities that a general theme doesn’t. You can also further extend the functionality through plugins.

#Loads Faster:

Since frameworks don’t contain any malicious code and heavy graphics, they load faster than standard themes. The high-quality code makes them load faster.


Most theme frameworks have their own communities of like-minded people. This helps you resolve common WordPress issues quickly.
