It just works and support is great

I manage two projects, one with WPML and one with Polylang.

WPML might have more features, but these come at a price, because WPML is slow and needs constant monitoring – to be honest, 90 % of issues the site has are created by WPML updates and feature changes.

Polylang on the other hand just works. It’s fast, reliable and includes most features you’d want, especially with Polylang Pro and the WooCommerce addon. Support is super fast and helpful as well. Highly recommended!
