Hybrid Core

You want a framework that puts you in control of your design, is 100% open source, and is completely $free to download? You’ve come to the right place. Hybrid Core is the framework of choice for serious developers.

Framework Features

The following is a small sampling of the available features within Hybrid Core.

Media Grabber

Hybrid Core comes with a custom-built media grabber. It allows you to pull video, audio, and gallery embeds directly from the post content. This is useful for displaying featured media for a post and is a perfect compliment to WordPress post formats.

Layouts API

The Layouts API is a system for handling layout options (e.g., left vs. right sidebar). Theme authors can register any number of layouts and have them automtically shown in the customizer for user selection. Per post/term layouts are possible too.

Font Loader

Core WordPress allows you to register and enqueue both scripts and styles. The font loader takes that a step further and allows you to do the same for fonts. By default, there’s built-in support for both Google Fonts and fonts bundled with the theme.

HTML Attributes

The attributes system is like WordPress’ body_class() and post_class() function on steroids. It’s works with any HTML attribute on any HTML element. There are built-in filter hooks and no limitations on how you can customize it.

Template System

From template-parts to post templates to the template hierarchy, Hybrid Core has it all. Don’t let WordPress’ default template system pigeon-hole you into an irrational structure because of weird, legacy support. Build and structure templates your way.

Media Meta

Did you know that WordPress stores metadata for images, audio, and video? Most theme authors don’t because WP doesn’t have an easy way to get the data. Hybrid Core makes it easy to get things like EXIF data and ID3 tags with its Media Meta API.


The framework comes bundled with the most-advanced breadcrumb script ever created for WordPress, Breadcrumb Trail, which is a separate plugin in its own right. It can handle anything you throw at it, no matter how complex the site.

Utility Functions

More than anything, Hybrid Core is a library or toolbelt of useful functions to help theme authors build better themes without having to worry about all of the dirty work in theme dev. The number of utility functions are worth using it alone.


Common questions about the Hybrid Core WordPress theme framework.

Who can use this framework?

Hybrid Core was primary built with WordPress theme developers in mind. Its purpose is help theme authors build better themes by handling some of the more complex features, allowing authors to simply get back to designing their themes.

Is this a parent theme?

No, it is not. Unfortunately, some savvy-marketers have co-opted the term “framework” and applied it to all sorts of things in the WP ecosystem. Hybrid Core is an actual framework that you install within your theme project to build from.

Do I have to pay anything to use it?

No. Hybrid Core is free to use, modify, and distribute under the terms of the GPL, version 2 or later. There are no costs associated with using or developing your own WordPress themes with it.

Do you provide support?

Support is provided on a year-to-year basis. For support, you’ll need to sign up for a developer membership to this site. All support requests are handled via the support forum or our Slack channel.
