ThemeRouter

ThemeRouter is a powerful WordPress plugin that allows multiple themes to coexist within a single WordPress installation and intelligently loads the correct theme for each request based on customizable routing rules.

Instead of changing the globally active theme, ThemeRouter dynamically routes requests server-side using conditions such as individual post/page, post types, or taxonomies. This makes it possible to run landing pages, redesign sections, campaign microsites, experiments, client previews, and hybrid theme architectures, all from one WordPress site.

Built for agencies, developers, and high-traffic production environments, ThemeRouter is engineered for stability, performance, and SEO safety. Only one theme is loaded per request, ensuring compatibility with caching systems, SEO plugins, WooCommerce, block themes, and modern WordPress workflows.

Whether you’re gradually redesigning a large website, testing conversion-focused layouts, or managing multiple frontend experiences without multisite complexity, ThemeRouter gives you precise control over theme rendering without compromising WordPress core behavior.
