WPML vs Weglot vs TranslatePress vs Polyglot
WPML vs Weglot vs TranslatePress vs Polyglot Translate: The Honest 2026 Comparison
Choosing a WordPress translation plugin is like choosing a phone plan. Everyone claims to be the best, pricing is deliberately confusing, and switching later is painful.
We're not going to pretend we're unbiased — we built Polyglot Translate. But we ARE going to be honest. Every plugin on this list is good. They just solve the problem differently. The right choice depends on YOUR site, YOUR budget, and YOUR priorities.
Here's the breakdown.
The Quick Answer
Don't have 14 minutes? Here's the cheat sheet:
| You are... | Best pick | |------------|-----------| | Small blog, 1-2 languages, zero budget | Polylang (free) or Polyglot Translate (free) | | Business site, want it done in 5 minutes | Weglot | | WooCommerce store, need full control | WPML or Polyglot Translate | | Agency managing multiple sites | Polyglot Translate (Bundle Agency) or WPML (Agency) | | Budget-conscious, long-term thinker | Polyglot Translate | | Visual editor lover | TranslatePress |
Now let's get into the details.
Pricing: The Real Numbers
This is where it gets interesting. These plugins use completely different pricing models.
A note on the numbers below: our own prices are exact and current. Competitor prices were checked against each vendor's own pricing page in 2026 — but plans change, so always confirm on their site before you buy. What doesn't change is the shape of each model, and that's what actually matters over a few years.
The pricing models, side by side
| Plugin | How it's priced (as of 2026) | What that means over time | |--------|------------------------------|---------------------------| | WPML | Annual license — Multilingual CMS €99/yr (3 sites) — plus a pool of 90K auto-translate credits you top up | Flat license; credits are consumable | | TranslatePress | Annual license — Business €199/yr (3 sites, 200K AI words) | Flat license; AI words are consumable | | Weglot | Monthly/annual subscription that scales with words + languages — Pro is $92/mo (~$1,100/yr) for 200K words, 5 languages | Recurring, grows with your content | | Polyglot Translate | Annual bundle (WordPress) or monthly plan (Cloud API); a shared Translation Memory | Recurring, but the memory means you re-pay less each cycle |
Note Weglot lists its prices in USD; everyone else here (including us) is in EUR.
Our WordPress pricing (exact)
Polyglot Translate's WordPress side is sold as annual bundles. Every bundle includes all five addons and a monthly pool of translation characters:
| Bundle | Price | Sites | Characters / month | |--------|-------|-------|--------------------| | Bundle ALL | €79/yr | 1 | 1M | | Bundle Pro | €129/yr | 3 | 1.5M | | Bundle Agency | €199/yr | 10 | 5M | | Bundle Agency+ | €299/yr | 25 | 10M |
Prefer to buy addons individually? Pro is €39/yr, WooCommerce €29/yr, Elementor €25/yr, SEO €25/yr, and Contact Form 7 support is free. And if you just want to try it, the free tier gives you 10,000 characters every month — no card required.
The hidden cost nobody talks about
Most translation plugins charge you the same amount forever for words you already translated. WPML and TranslatePress give you translation credits that refresh with each cycle — use them or lose them, and buy more when you grow. Weglot's subscription scales up as your content and traffic grow.
Polyglot Translate works differently. Its Translation Memory stores every translation. The first time you translate a string, it costs characters. Every later request for that same string is served instantly from your own memory — and duplicate strings on a page are deduplicated locally before any cloud call is even made. So the characters you spend early permanently reduce what you need later.
For a store whose catalog is fairly stable, that means your effective bill trends down over time instead of staying flat.
Setup & Ease of Use
WPML: Powerful but Complex
WPML is the Swiss Army knife of translation plugins. It can do almost anything — but that power comes with complexity.
Setup takes 15-30 minutes for a basic configuration. More if you're adding WooCommerce, page builder support, or custom post types. The admin interface is comprehensive but can feel overwhelming. There are settings pages inside of settings pages.
For developers and power users: WPML is excellent. For a small business owner who just wants their site in Spanish? It's overkill.
Setup time: 15-30 minutes Learning curve: Medium-high
Weglot: Instant But Limited
Weglot is the opposite of WPML. Install, enter your API key, pick languages. Done. Your site is translated in under 5 minutes.
The magic is in the cloud-based approach — Weglot detects all content on your pages and translates it automatically. You edit translations through their dashboard or directly on your site.
The trade-off: you don't own the translations. They live on Weglot's servers. Cancel your subscription and your translated content disappears.
Setup time: < 5 minutes Learning curve: Low
TranslatePress: Visual and Intuitive
TranslatePress has the best visual translation editor in the market. You literally browse your site and click on any text to translate it. What you see is what you get.
Setup is straightforward — 10 minutes for basic configuration. The visual editor makes translation management genuinely enjoyable (as enjoyable as translation management can be, anyway).
The downside: no one-click "translate everything" button in the free version. You translate page by page, string by string, unless you buy AI translation credits.
Setup time: 10 minutes Learning curve: Low-medium
Polyglot Translate: Fast Setup, Smart Long-Term
Install from WordPress.org, enter your API key, choose languages. Similar to Weglot's ease of setup, but translations live in YOUR database, not on someone else's server.
The Pro addon's Magic Translate button translates your entire site with one click — homepage first, then pages, then posts, with background processing. You can close your browser and come back later.
The unique angle: Translation Memory stores everything. First translation costs characters. Every subsequent request for the same content is instant and free.
Setup time: < 5 minutes Learning curve: Low
Database & Performance
This matters more than most people think.
WPML: The Duplicate Post Problem
WPML creates duplicate posts for each language. A 100-page site in 5 languages becomes 500 posts in your database. Your wp_posts table grows 5x. Sitemaps get messy. Database queries slow down. Managing content becomes a nightmare.
Is this a dealbreaker? For small sites, no. For WooCommerce stores with 1,000+ products in 10 languages? Your database is now 10,000+ posts. That affects performance.
Weglot: Cloud-First, No Database Impact
Weglot stores nothing in your WordPress database. Translations live on their cloud servers and are injected into your pages dynamically.
Pros: Zero database bloat. No impact on your database performance. Cons: You don't own the translations. Extra HTTP requests to Weglot's servers on every page load (cached, but still). If Weglot goes down, your translations disappear. Cancel and everything is gone.
TranslatePress: Clean Database Approach
TranslatePress stores translations in a dedicated custom table (trp_translations). No duplicate posts. Clean database structure. Good performance characteristics.
Similar to Polyglot Translate's approach, and significantly better than WPML's duplicate post model.
Polyglot Translate: Cache-First Architecture
Like TranslatePress, Polyglot Translate uses a dedicated translations table. No duplicate posts. But it goes further with a cache-first architecture: translated content is served from local cache, never from external API calls on page load.
First visit triggers translation (if not already in your Translation Memory). Every subsequent visit: instant, from cache. No external API call per page view.
Performance ranking (least to most database impact):
- Weglot (zero DB impact, but cloud dependency)
- Polyglot Translate (dedicated table + cache-first)
- TranslatePress (dedicated table)
- WPML (duplicate posts — heaviest)
WooCommerce Support
If you're running an online store, this section matters.
| Feature | WPML | Weglot | TranslatePress | Polyglot | |---------|------|--------|----------------|----------| | Product translation | ✓ | ✓ | ✓ | ✓ | | Variable products | ✓ | ✓ | ✓ | ✓ | | Cart & checkout | ✓ | ✓ | ✓ | ✓ | | Order emails | ✓ | ✓ | Partial | ✓ (9 types) | | My Account area | ✓ | ✓ | Partial | ✓ | | URL slug mapping | ✓ | ✓ | ✓ | ✓ | | REST API | ✓ | ✗ | ✗ | ✓ | | HPOS compatible | ✓ | ✓ | ✓ | ✓ | | Included in base price | CMS tier only | All plans | All plans | WooCommerce addon (€29/yr) or any Bundle |
WPML has the deepest WooCommerce integration — it's been doing this the longest. Polyglot Translate matches most WPML features with the added benefit of Translation Memory. Weglot handles it through their cloud proxy. TranslatePress covers the basics but has gaps in email translation.
SEO & Multilingual Search
| Feature | WPML | Weglot | TranslatePress | Polyglot | |---------|------|--------|----------------|----------| | Hreflang tags | ✓ | ✓ | ✓ (addon) | ✓ | | Translated URLs | ✓ | ✓ | ✓ | ✓ | | Translated meta | ✓ | ✓ | ✓ | ✓ (addon) | | JSON-LD schema | ✗ | ✗ | ✗ | ✓ (addon) | | XML sitemap | ✓ | ✓ | ✓ | ✓ | | Yoast/RankMath | ✓ | ✓ | ✓ | ✓ | | Canonical URLs | ✓ | ✓ | ✓ | ✓ |
All four handle the SEO basics well. Polyglot Translate's SEO addon is the only one that translates JSON-LD structured data — useful for rich snippets in multiple languages.
Translation Quality
Machine Translation Sources
| Plugin | Engines Used | |--------|-------------| | WPML | DeepL, Google, Microsoft (via credits) | | Weglot | DeepL, Google, Microsoft + custom AI layer | | TranslatePress | DeepL, Google, Microsoft (via credits) | | Polyglot | Self-hosted OPUS-MT (primary), Gemini (cloud), and Argos as a fallback |
Polyglot Translate runs a provider cascade: a self-hosted OPUS-MT model first, Gemini in the cloud when a language pair needs it, and Argos as a final fallback — quality-sorted, so the best available engine wins. Because OPUS-MT is self-hosted, a large share of translations never touch a shared third-party cloud API at all.
Quality Improvement Over Time
This is Polyglot's real differentiator. Translations aren't just stored — they're graded and they climb a trust ladder based on real signals:
- Origin — where did this translation come from (a trusted human, the cascade, community)?
- Community feedback — did users accept, reject, or edit it?
- Trust tier — every translation starts as a candidate, is promoted to verified, and the best reach gold; bad ones get demoted.
- Freshness — recently confirmed translations are trusted more than stale ones.
The result is a Translation Memory that gets better the more your site (and the wider community using the shared memory) uses it. No other plugin on this list works this way.
What You DON'T Own
This is the question nobody asks until it's too late.
| Plugin | Who owns translations? | What happens if you cancel? | |--------|----------------------|---------------------------| | WPML | You (in your DB) | Translations stay | | Weglot | Weglot (their servers) | Translations disappear | | TranslatePress | You (in your DB) | Translations stay | | Polyglot | You (in your DB) | Translations stay |
Weglot's cloud model means your translations live on their infrastructure. Cancel your subscription and your multilingual site becomes monolingual overnight. For a business depending on international traffic, this is vendor lock-in with real consequences.
WPML, TranslatePress, and Polyglot all store translations in your WordPress database. Cancel any of them and your existing translations remain.
