Opis
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 Osom Studio, 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.
When you need this
- Landing pages with a unique design — without touching your main theme
- WooCommerce stores running a dedicated shop theme alongside a corporate theme
- Membership or gated sections with a separate visual identity
- Theme testing — preview a new theme on specific pages before switching site-wide
- Agencies managing multi-brand WordPress installations from a single dashboard
Key features
- Flexible rules — assign themes by page, post, post type, custom URL, category, or tag
- Full theme loading — the alternative theme’s functions.php loads completely, so page builders (Elementor, Divi, Beaver Builder) and custom functionality work as expected
- Admin theme switcher — access settings for any installed theme directly from the admin bar
- Per-user admin theme — each administrator can use their preferred dashboard theme independently
- Draft & scheduled support — apply themes to unpublished content for preview and staging
- REST API support — configure custom REST API prefixes per theme
- ACF compatible — loads Advanced Custom Fields JSON from all active theme directories
- No code required — set up everything through the WordPress admin panel
How it works
- Install and activate the plugin
- Go to Appearance > Theme Switcher
- Select a rule type (Page, Post, Post Type, Category, Tag, or Custom URL)
- Choose the content to target
- Pick the alternative theme
- Click Add Rule — changes apply immediately
The plugin hooks into WordPress on the setup_theme action, before any theme code runs. This ensures full compatibility with theme features, widgets, customizer settings, and page builders.

Najczęściej zadawane pytania
-
Does this affect my site’s main theme?
-
No. Your main active theme remains unchanged for all pages that don’t have a specific rule. Only the pages, posts, or URLs you configure will use an alternative theme.
-
Can each admin user have their own dashboard theme?
-
Yes. The admin bar theme switcher stores preferences per user. Each administrator can view the WordPress dashboard with their preferred theme without affecting other users or the frontend.
-
Does the alternative theme’s functions.php load?
-
Yes. The plugin switches themes early in the WordPress loading process (on the
setup_themehook), ensuring the alternative theme’s functions.php and all its features load correctly. -
Will this work with my page builder?
-
Yes. Since the full theme is loaded (not just styles), page builders like Elementor, Divi, and Beaver Builder work correctly with the alternative theme.
-
Can I apply a theme to all products in WooCommerce?
-
Yes. Use the „Post Type” rule type and select „Products” to apply a theme to all WooCommerce products and the shop archive.
-
Does it work with caching plugins?
-
Most caching plugins work correctly. However, if you experience issues, you may need to exclude pages with alternative themes from the cache or use a caching plugin that supports conditional caching.
-
Can I use this for A/B testing themes?
-
While not designed specifically for A/B testing, you can apply different themes to specific URLs and manually direct traffic to test user preferences.
-
Is this plugin compatible with WordPress multisite?
-
The plugin is designed for single-site WordPress installations. For multisite setups, WordPress already provides per-site theme management. If you have a specific multisite use case, let us know through the support forum.
