Cornerstone – The WordPress Page Builder

Cornerstone is a visual page builder for WordPress developed by Themeco, designed so you can create, edit, and customize your site's layout directly from the front-end, without needing to switch between the admin panel and the preview. Its philosophy is simple: what you see is exactly what you get, making the design process a fluid, fast, and frictionless experience.

It is intended both for developers and agencies seeking total control over every element, and for users without technical knowledge who want to build professional pages without writing a single line of code. With its drag-and-drop interface, you can add sections, columns, and predefined elements with total freedom, and adjust every detail through intuitive inspection panels.

The plugin includes more than 100 fully customizable elements, ranging from standard design elements to dynamic components and specific elements for online stores. Additionally, its Component Builder allows you to create your own reusable elements from scratch and save them to your personal library for use in any future project.

One of its great strengths is the ability to consume dynamic data from your entire WordPress site, including post metadata, user data, and even information from third-party plugins like Advanced Custom Fields. Thanks to its Loopers system, you can iterate through and display this data in a structured way, opening up a huge range of possibilities for complex sites.

Cornerstone also stands out for its element-level effect controls, which let you apply filters, transformations, interactions, masks, and blend modes natively, without relying on external extensions. This helps you bring your designs to life and improve the user experience for your visitors.

The editor is organized into two main areas: the work area, where you manage the structure and settings, and the preview area, clean and distraction-free, where you inspect and reposition elements directly. Text editing is inline, so you can modify typography, formats, and styles in real time, and the integrated code editors allow advanced users to see how their CSS and JavaScript customizations are reflected instantly.

With support for fully responsive design, preview modes for desktop, tablet, and mobile, and an active, collaborative community, Cornerstone positions itself as a complete solution for those looking to build modern, fast, and visually striking websites on WordPress.
