WPML vs Polylang

WPML wins for SMB ecommerce in 2026; Polylang wins for hands-on dev teams that want a free core. For an Amazon FBA EU seller running 4 languages on a 100-product WooCommerce catalogue, WPML Multilingual CMS at $99/year delivers WooCommerce integration, AI credits, and string translation in a single licence. Polylang's free core plus Polylang Pro at €99/year matches the price but expects you to wire the ecommerce layer manually — typically 8-15 hours of dev time before launch. Choose WPML if you bill clients; choose Polylang if you bill yourself.

At a glance: WPML vs Polylang

WPML is the all-in-one paid plugin; Polylang is the free core with a paid Pro upgrade. Both produce SEO-correct hreflang on indexable subdirectories. The 2026 head-to-head:

Axis	WPML	Polylang
Free tier	None	Yes — full core plugin
Entry licence	$39/yr Multilingual Blog	Free, or €99/yr Pro
WooCommerce	Native, deep	Add-on (Polylang for WooCommerce €99/yr)
AI translation credits	Included (90k-180k)	Manual DeepL API key
String translation	Native UI	Pro only
Hreflang	Strong, automatic	Strong, automatic
WP admin integration	Deep	Native
Setup time (4 langs)	2-4 hours	6-15 hours
Maintenance burden	Low — single plugin	Higher — multi-plugin stack
Multilingual schema/SEO	Yoast/Rank Math hooks	Yoast/Rank Math hooks

Both plugins translate content in the WordPress database itself — unlike Weglot or Linguise, which sit as a JavaScript or proxy layer. That means translated content lives in your database, survives plugin removal, and behaves predictably on backups. The trade-off is that you maintain the translation infrastructure yourself.

Pricing compared

Polylang is free at the core level; WPML is paid-only but bundles features Polylang sells as add-ons. WPML's published ladder runs $39 Multilingual Blog → $99 Multilingual CMS → $199 Multilingual Agency, per wpml.org/purchase. Polylang runs Free Core → €99/year Polylang Pro per site, plus €99/year Polylang for WooCommerce, per polylang.pro.

Equivalent-bracket comparisons:

• Blog / content site, no ecommerce: Polylang Free covers it. WPML Multilingual Blog at $39/year. Polylang wins on price.
• Single-site WooCommerce, 4 languages: WPML Multilingual CMS at $99/year (includes WooCommerce Multilingual + 90k AI credits). Polylang Pro €99 + Polylang for WooCommerce €99 = €198/year. WPML wins.
• 3 sites, full ecommerce stack: WPML Multilingual CMS covers 3 sites at $99/year. Polylang Pro charges per site — €297/year for 3 sites + €297 for WooCommerce add-on. WPML wins by ~€500/year.
• Agency, unlimited client sites: WPML Multilingual Agency at $199/year. Polylang offers no equivalent unlimited-site licence. WPML wins.

The math flips only on free, content-only blogs where Polylang's free core costs nothing. Once you cross WooCommerce, multi-site, or AI translation needs, WPML's bundle is cheaper. See website translation cost for the full picture including engine and review costs.

Translation quality compared

Both plugins are translation managers, not translation engines. Quality depends on which engine you wire to — DeepL, Google, Microsoft, or human translators. WPML ships AI translation credits in the box (Multilingual CMS includes 90,000 credits/year). Polylang requires you to bring your own API key.

WPML's bundled AI routing produces a 21% German edit rate on standard product copy — a fraction worse than Weglot's 19%. Polylang Pro paired with DeepL API runs about 23% because the integration skips content-type-aware routing. Both gaps close to under 5% with native review on top. The CSA Research benchmark via Slator confirms DeepL beats Google by 11+ BLEU points on European pairs — both plugins let you wire DeepL, so the engine choice matters more than the plugin. Where WPML wins is speed: AI translation in the dashboard runs as a one-click batch. Polylang expects you to script the DeepL API or use a bridge plugin. For a WooCommerce store doing FBA EU, WPML's batch translation saves 4-6 hours per launch cycle. Both plugins support glossaries on Pro tiers.

Operational overhead compared

WPML installs and configures in under an hour for a 4-language site; Polylang takes 6-15 hours of dev time for the same configuration once WooCommerce is involved. The difference is bundle vs build-your-own.

WPML's setup wizard configures languages, hreflang, URL structure, WooCommerce, taxonomies, and AI engine routing in a single flow. Polylang requires installing 2-4 plugins (Polylang Pro, Polylang for WooCommerce, optionally a DeepL bridge), then manually configuring each. Hreflang implementation is comparable on both — Yoast and Rank Math integrate cleanly with both plugins, and both produce the canonical pattern Google specifies in their hreflang documentation. Maintenance burden differs: WPML's single licence means one update cycle; Polylang's multi-plugin stack means three or four update cycles with version-compatibility checks. For agencies, WPML's predictability wins. Polylang wins when you have an in-house dev who prefers transparent, auditable code.

Best-fit by use case

Pick the plugin that matches your budget, dev team, and ecommerce ambitions. Both work; the operational profiles differ.

Personal blog, 1-2 languages. Polylang Free. Zero cost, full hreflang, basic content translation.

SMB content site, 3+ languages. WPML Multilingual Blog at $39/year. Cheaper than Polylang Pro and includes AI credits.

Amazon FBA EU seller (DE/FR/IT/ES) on WooCommerce. WPML Multilingual CMS at $99/year. Native WooCommerce translation, 90k AI credits cover the catalogue, hreflang automatic, string translation built in. The setup time saved (8-12 hours) more than offsets any quality gap vs Linguise. See Amazon FBA Germany website for the integrated launch checklist.

Agency managing 5+ client sites. WPML Multilingual Agency at $199/year. Unlimited sites, full feature set, single dashboard. Polylang has no comparable agency licence — you'd buy Pro per site at €99 each.

Frequently asked questions

Is WPML worth the money over free Polylang?

Yes — for any site running WooCommerce, multi-site licensing, or AI translation. WPML Multilingual CMS at $99/year bundles WooCommerce Multilingual ($79/year if bought separately for Polylang), 90,000 AI translation credits, string translation, and a setup wizard. Polylang's free core covers content translation but expects you to wire WooCommerce, AI, and strings yourself — typically €198/year in plugins and 6-15 hours of dev time. For blogs and brochure sites with no commerce, Polylang Free wins. For ecommerce, WPML wins.

Which produces better SEO?

Tied. Both plugins write hreflang return tags, register translated URLs in the sitemap, and integrate with Yoast and Rank Math for canonical handling. The SEO risk in 2026 isn't from the plugin — it's from publishing AI translation at scale without native review, which Google's ranking systems flag regardless of which plugin produced the output. WPML's setup wizard makes correct configuration easier; Polylang gives you more manual control. See machine translation SEO penalty for the wider picture.

Can I switch from Polylang to WPML, and which is faster to set up?

WPML ships an official Polylang import tool that migrates languages, posts, pages, taxonomies, and strings — typically 30-60 minutes for an SMB site, though WooCommerce products need a manual audit afterwards. On setup speed, WPML wins by 4-13 hours on a 4-language WooCommerce site. WPML's wizard configures languages, hreflang, URL structure, AI engine, WooCommerce product translation, and taxonomy translation in a single flow. Polylang requires Polylang Pro, Polylang for WooCommerce, and a DeepL bridge configured separately. Our team handles tool migrations as part of a done-for-you engagement — flat fee, redirect map handed back. For a WordPress site you want multilingual fast, WPML is the lower-friction pick.

Is Polylang really free forever?

Yes — Polylang core is GPL-licensed and free indefinitely. It covers content translation, language switcher, hreflang, and language-specific URLs. Paid upgrades (Polylang Pro €99/year, Polylang for WooCommerce €99/year) add string translation, REST API, and ecommerce product translation. For a hobbyist blog, the free core is sufficient. For ecommerce, plan to budget €198/year minimum.

Which handles WooCommerce better — WPML or Polylang?

WPML, by a wide margin. WPML Multilingual CMS includes WooCommerce Multilingual as a bundled module — products, variations, attributes, taxonomies, payment gateways, and shipping translate from a single dashboard. Polylang requires the separate Polylang for WooCommerce add-on at €99/year, which works but variations and attribute terms need manual configuration. For ecommerce website translation on WordPress, WPML is the default pick.
