Slim Language Switcher helps you present the same content in multiple languages without replacing WordPress’s own language files.
Add the languages you support, assign a default URL to each one, then optionally override those URLs on posts, pages, products, and terms. The plugin outputs a language switcher (shortcode or block) and can print hreflang tags plus JSON-LD for search engines.
Features
- Language directory stored in WordPress options (no custom database tables)
- Light, dark, and auto themes with editable color palettes
- Dropdown, list, and inline layouts
- Live appearance designer with a copyable shortcode
- Language Switcher block with layout and theme controls
- Alternate URL fields on posts, pages, public post types, and public taxonomies
- Optional WooCommerce shop, product category, and product tag support
- Optional hreflang and JSON-LD output
This plugin does not translate content automatically. Pair it with translated pages or a separate translation workflow.
