Osom Multi Theme Switcher lets you run multiple WordPress themes on a single site — assigning different themes to specific pages, posts, post types, categories, tags, or custom URLs.
Built by <a href="https://www.osomstudio.com" rel="nofollow ugc">Osom Studio</a>, a WordPress & WooCommerce agency with 10+ years of experience managing complex multi-theme setups for clients.
We built this plugin because we kept solving the same problem for clients: one WordPress installation, multiple designs. Landing pages that need a completely different look. A WooCommerce store that runs a separate theme from the corporate site. A membership area with its own design system.
Instead of hacking theme conditionals into functions.php every time, we packaged our solution into a plugin.
<h4>When you need this</h4>
<ul>
<li>Landing pages with a unique design — without touching your main theme</li>
<li>WooCommerce stores running a dedicated shop theme alongside a corporate theme</li>
<li>Membership or gated sections with a separate visual identity</li>
<li>Theme testing — preview a new theme on specific pages before switching site-wide</li>
<li>Agencies managing multi-brand WordPress installations from a single dashboard</li>
</ul>
<h4>Key features</h4>
<ul>
<li>Flexible rules — assign themes by page, post, post type, custom URL, category, or tag</li>
<li>Full theme loading — the alternative theme’s functions.php loads completely, so page builders (Elementor, Divi, Beaver Builder) and custom functionality work as expected</li>
<li>Admin theme switcher — access settings for any installed theme directly from the admin bar</li>
<li>Per-user admin theme — each administrator can use their preferred dashboard theme independently</li>
<li>Draft & scheduled support — apply themes to unpublished content for preview and staging</li>
<li>REST API support — configure custom REST API prefixes per theme</li>
<li>ACF compatible — loads Advanced Custom Fields JSON from all active theme directories</li>
<li>No code required — set up everything through the WordPress admin panel</li>
</ul>
<h4>How it works</h4>
<ol>
<li>Install and activate the plugin</li>
<li>Go to Appearance > Theme Switcher</li>
<li>Select a rule type (Page, Post, Post Type, Category, Tag, or Custom URL)</li>
<li>Choose the content to target</li>
<li>Pick the alternative theme</li>
<li>Click Add Rule — changes apply immediately</li>
</ol>
The plugin hooks into WordPress on the <code>setup_theme</code> action, before any theme code runs. This ensures full compatibility with theme features, widgets, customizer settings, and page builders.
