Slim Language Switcher – Multilingual Manager with hreflang SEO Tags

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.
