Polylang vs TextUnited

Polylang is a WordPress plugin for building multilingual websites and translating WordPress content. It handles pages, posts, media, categories, tags, custom post types, menus, and widgets, with language URLs arranged as subdirectories, subdomains, or separate domains. Polylang Pro supports manual translation and DeepL machine translation using the customer's own API key. Pro also offers language switchers, browser-language detection, translated URL slugs, hreflang and Open Graph tags, and language-specific meta tags. It integrates with the WordPress block editor and Site Editor and supports the REST API and XLIFF translation-project import and export. Listed integrations include WooCommerce and Yoast SEO. The free WordPress plugin costs nothing; Pro licenses start at €99 a year, ex VAT. A multilingual WooCommerce shop also needs the Polylang for WooCommerce add-on. DeepL is not currently compatible with Elementor and some builders, and there is no one-click translate-everything feature.

TextUnited is a language platform for companies managing multilingual product, software, technical documentation, marketing, legal, and localization work. Teams can run self-service projects and file translations, connect through the API, use automation platforms, or work with an MCP Server. Its AI localization widget applies company terminology, tone, and writing style, while human linguists review high-impact copy and low-scoring segments. The API supports more than 120 languages, including dialects and right-to-left languages, and accepts files, strings, JSON, and XML through REST endpoints. The service preserves PDF, DOCX, HTML, XML, Markdown, and XLIFF formatting, including layouts, placeholders, and metadata. Listed API use cases include GitHub CI pipelines, Contentful, Sitecore, Git repositories, Sanity CMS, Next.js, Salesforce, and legacy apps. TextUnited says its API is SOC 2-compliant, GDPR-ready, AES-256 encrypted, hosted on dedicated IBM Cloud infrastructure, and includes granular access controls and audit trails. Customer data remains in the selected region, according to the company. The free plan includes 15,000 words and 15 PDF pages per month for one user. TEAM is 150€/mo; OnePlatform is 780€/mo.
