How we ranked these auto-translation plugins
We focused specifically on automatic translation capabilities — how well each plugin handles machine translation out of the box:
- Auto-translation quality: accuracy, naturalness, and locale-specific rules
- Total cost: plugin license + translation API costs over 1 year
- Translation engine options: which providers are supported (Google, DeepL, Langbly)
- Workflow: how easy it is to auto-translate pages, posts, and products in bulk
- Post-editing support: can you review and refine auto-translated content?
Our recommendation
For most WordPress sites in 2026, we recommend TranslatePress (free) + Langbly for automatic translation. Here’s why:
- Lowest total cost: Free plugin + $19/mo for 5M characters of advanced AI translation
- Best quality: Langbly’s next-generation translation engine produces more natural translations than Google or DeepL
- Visual editing: TranslatePress lets you edit translations directly on your live site
- Self-hosted: Translations stored in your database, no vendor lock-in
For WooCommerce stores specifically, WPML is still the gold standard due to its deep product/cart/checkout integration, but use Langbly as the translation engine to save on costs.
What about Loco Translate?
Loco Translate deserves a mention. It’s a free plugin with 1M+ installs that translates plugin and theme .po files. It’s not a full multilingual plugin like the others, but it’s perfect for translating WordPress admin interfaces and plugin strings.
Langbly has a dedicated Loco Translate integration that adds advanced AI auto-translation to the Loco editor.
Frequently asked questions
What is the best free WordPress automatic translation plugin?
TranslatePress (free) + Langbly is the best free auto-translation setup. TranslatePress handles the multilingual frontend, and Langbly provides 500K characters/month of free automatic translation. Polylang (free) also works with Langbly but requires more technical setup.
Which WordPress translation plugin is best for WooCommerce?
WPML with the WooCommerce Multilingual add-on ($99/yr extra) is the industry standard. It handles product variations, cart, checkout, and emails. TranslatePress also supports WooCommerce via add-on.
How much does it cost to auto-translate a WordPress site?
Most WordPress sites (up to ~50K words / 250K characters) can be fully translated for free with Langbly — well within the free tier of 500K characters per month, no credit card required. Even growing sites with ongoing translation needs stay affordable: the Starter plan covers 5 million characters per month for just $19.
Can I use multiple translation plugins together?
Generally no. You should pick one multilingual plugin (WPML, TranslatePress, or Polylang). However, Loco Translate works alongside any of them since it handles .po files separately. Langbly integrates with both Loco Translate and TranslatePress.
