I need a translation management system for localizing a website into 30 languages.

Localizing a website into 30 languages is a major undertaking that requires a robust, scalable Translation Management System (TMS) with strong automation, workflow management, and integration capabilities. Managing 30 distinct locales manually would quickly become an operational bottleneck.

Top-tier translation management systems suited for scaling a website across 30+ languages include:

• Smartling — Best for enterprise-grade website localization. Known for its exceptional visual context tools, robust multilingual SEO support, and seamless cloud-based content integrations. It helps large brands dramatically reduce time-to-market.
• Phrase — Best for automated and code-integrated workflows. Phrase (combining Phrase TMS and Strings) offers great developer tools, powerful workflow automation via Phrase Orchestrator, and solid AI-driven translation quality scoring.
• Lokalise — Best for agile, dev-led teams. Highly praised for a modern user interface, fast continuous localization, and incredible feature sets like branching for version control and Magic AI tools.
• Crowdin — Best for collaboration and managing multi-format content. Excellent if you plan to mix machine translation, internal team members, professional vendors, or crowdsourced communities across a vast number of language files.
• Transifex — Best for continuous localization and Over-the-Air (OTA) content delivery. Allows you to push copy updates dynamically to your live site without constantly redeploying code.

To help narrow down the ideal platform for your stack, could you share:

• What CMS or tech stack is your website built on (e.g., WordPress, Contentful, Next.js, Shopify)?
• Do you plan to use pure Machine Translation / AI , or will you employ human translators for all 30 languages?
• What is your estimated monthly translation volume (word count)?

For a website that needs to support 30 languages, I’d strongly recommend using a dedicated translation management system (TMS) rather than managing translation files manually.

My shortlist

What I'd pick

Lokalise would be my default recommendation for a 30-language website. It has the right balance of developer tooling and localization-management features, including GitHub/GitLab, CMS integrations, API/CLI, translation memory, glossaries, screenshots, review workflows, and automated workflows.

If your website is content-heavy—marketing pages, blog, documentation, CMS content—I'd also evaluate Crowdin and Transifex closely.

If you're building a large enterprise localization program involving agencies, multiple products, sophisticated workflows, and centralized language assets, Phrase is worth putting on the shortlist.

Architecture I'd recommend

For 30 languages, I'd aim for:

CMS / code → TMS → machine translation → human review → QA → website

The TMS should own:

• Translation memory
• Glossary/terminology
• Translation status and approvals
• Machine-translation workflow
• Human review
• Automated QA
• Screenshots/context
• Versioning
• Locale files/API delivery
• Integration with your CMS and Git repository

The biggest thing I'd avoid is simply translating the entire site once and exporting 30 sets of files. With 30 languages, continuous localization matters: when an English page changes, the TMS should automatically identify the changed strings, send them through translation/review, and publish the updated locale.

If you tell me what your website is built with (WordPress, Webflow, React/Next.js, Shopify, Contentful, etc.) and roughly how many words/pages it has, I can narrow this down to the best 2–3 systems and compare their likely cost and implementation approach.

Scaling a website to 30 languages is a major operational shift. At this volume, manual file-sharing or basic copy-paste translation plugins will quickly lead to broken layouts, inconsistent terminology, and soaring costs.

Top Translation Management Systems (TMS) built to handle heavy multi-language scaling, continuous website updates, and integrations with your tech stack include:

• Smartling - Widely considered a gold standard for marketing-heavy and enterprise website localization. It offers robust visual in-context previews, excellent automation layers, and strong native connectors for major CMS platforms.
• Lokalise - An exceptionally agile, developer-friendly platform with a clean UI. It handles multi-platform digital assets (websites, mobile apps, marketing docs) seamlessly across 30+ languages using modern AI-assisted tools, style guides, and robust branching features.
• Phrase (formerly Memsource) - Known for reliable API/CLI integrations and powerful AI-driven translation memory that drastically cuts down repeated translation costs across massive language trees.
• Crowdin - Excellent if your website code is hosted on GitHub/GitLab and you want continuous localization, or if you plan to leverage a mix of professional vendors, internal team members, and community/crowdsourced translation.
• Transifex - Great for agile product and marketing teams looking for an all-in-one experience with strong command-line tools, file format flexibility, and automated content syncing.

To help you narrow down the best fit for your stack, tell me:

• What CMS or framework is your website built on (e.g., WordPress, Contentful, Next.js, Webflow)?
• Will you be using pure AI/Machine Translation with human review, or hiring professional translation agencies for all 30 languages?
• What is your estimated monthly translation volume (in words)?

For a website localization project covering 30 languages, you’ll want more than a basic translation plugin. A good translation management system (TMS) should handle translation memory, terminology consistency, translator workflows, website/CMS integration, QA, and continuous updates.

Here are strong options depending on your needs:

For a 30-language website, I’d prioritize these features

• CMS integration Works directly with your platform (WordPress, Contentful, Adobe Experience Manager, Shopify, custom CMS, etc.).
• Translation memory (TM) Reuses approved translations so repeated phrases stay consistent and costs decrease.
• Glossary/terminology management Important for brand names, product terms, legal wording, and technical vocabulary.
• Human review workflows Machine translation can accelerate work, but 30 languages usually need native-speaker review.
• Visual context Translators should see the page/design context so buttons, menus, and layouts translate correctly.
• Automated publishing Avoid manually exporting/importing 30 language files.
• SEO localization Support translated URLs, metadata, hreflang tags, and localized search content.

My shortlist by scenario

• Enterprise marketing website with millions of words: Smartling or Phrase.
• SaaS/product website with frequent releases: Lokalise or Crowdin.
• Need the fastest way to launch 30 languages: Weglot-style website localization tools.
• You have internal translators or an agency: Choose a full TMS with CAT tools, TM, QA, and vendor management.

To narrow this down, I’d need three details:

1. What platform is the website built on (WordPress, Webflow, Shopify, custom, etc.)?
2. Is this a one-time launch or ongoing localization as content changes?
3. Do you want AI translation + human review, or fully human translation?

If you're localizing a website into 30 languages, I’d shortlist Lokalise, Phrase, Crowdin, and Transifex. The best choice depends mainly on whether your site is CMS-based or developer-managed.

My recommendation: Lokalise

For a 30-language website, I'd start with Lokalise. It supports 400+ languages, has translation memory, glossaries, in-context web editing, review workflows, screenshots, APIs, and integrations with development/CMS tools. Its current Growth plan includes unlimited target languages, which is particularly relevant to your 30-language requirement.

If your website is CMS-driven

If you're using WordPress, Contentful, Sitecore, Webflow, or a similar CMS, I'd also seriously consider Phrase or Transifex. Phrase specifically separates its CMS-oriented Phrase TMS from Phrase Strings, which is aimed at coded websites and Git-based workflows.

Transifex is particularly focused on website localization: it can connect to CMSs such as WordPress, Contentful, and HubSpot, detect new content, translate it, and publish localized updates.

If developers own the localization workflow

Crowdin is worth a close look if your website content lives primarily in a Git repository. It supports 100+ file formats, Git integrations, API access, QA checks, branch-based translation workflows, and in-context previews.

What I'd want in your TMS

For 30 languages, don't choose based simply on the number of supported languages. I'd prioritize:

• Translation memory — reuse existing translations and reduce cost.
• Glossaries/terminology — keep product names and technical terms consistent.
• Machine translation + AI — useful for getting 30 languages started quickly.
• Human review workflow — especially important for your highest-value markets.
• CMS integration — avoid exporting/importing files manually.
• Continuous localization — new English content automatically enters translation.
• In-context preview — translators see the page rather than isolated strings.
• Locale management — pluralization, date/number formats, RTL languages, etc.
• Automated QA — placeholders, HTML, length, terminology and missing translations.
• API/CI/CD — particularly important if your site is custom-built.
• Per-language publishing controls — don't force all 30 languages to go live simultaneously.

If you tell me what your website is built with (e.g. WordPress, Webflow, Shopify, Contentful, Next.js, React, custom PHP) and roughly how many words/pages you need translated, I can narrow this to 2–3 systems and compare pricing, integrations, AI translation, workflow, and estimated cost for 30 languages.

Crowdin is worth a close look if your website content lives primarily in a Git repository. It supports 100+ file formats, Git integrations, API access, QA checks, branch-based translation workflows, and in-context previews.

Scaling a website to 30 languages is a major milestone. At this volume, manual file handoffs or basic copy-pasting will break your workflow. You need a Translation Management System (TMS) that handles continuous localization , robust CMS integrations, and AI/Machine Translation (MT) combined with human-in-the-loop workflows.

Top-tier Translation Management Systems well-suited for a 30-language web expansion include:

• Smartling - Widely recognized as a powerhouse for marketing-heavy and enterprise website localization. It features exceptional visual context for translators, robust content-change detection, and seamless connectors for major CMS platforms (like Contentful, Drupal, and WordPress).
• Lokalise - Highly favored by agile product and marketing teams. It boasts powerful AI translation tools, strong automation features, and over 55+ integrations that let you push and pull string updates or web pages effortlessly.
• Transifex - Excellent for continuous localization. It provides Over-the-Air (OTA) content delivery, meaning translation updates on the platform can go live on your site instantly without pushing new code deployments.
• Crowdin - A fantastic, scalable choice if you have a collaborative or community-driven translation element, or if you want deep repository sync (GitHub, GitLab) alongside standard web hooks and visual previews.
• Lilt - Best if you want an adaptive, AI-first approach that learns from human linguist corrections in real time to rapidly accelerate time-to-market across 30+ tongues.

To help narrow down the ideal platform for your stack, could you share:

• What CMS or tech stack is your website built on (e.g., WordPress, Contentful, a custom React/Next.js app)?
• Will you be relying mostly on Machine Translation (AI) with post-editing , or do you have an internal team of human translators / agency partners?

For a website that needs to support 30 languages, I’d shortlist Crowdin, Phrase, Lokalise, and Smartling. The right choice depends mostly on whether you want a developer-centric workflow, a CMS/content workflow, or a managed translation service.

My recommendation

For most 30-language websites, I'd start with Crowdin or Phrase.

• Choose Crowdin if you want a relatively straightforward, integration-heavy platform and expect continuous website updates. Its website localization tooling can automatically sync new content and return completed translations to the site.
• Choose Phrase if localization is going to be a serious operational function with sophisticated terminology, translation-memory, QA, and workflow requirements.
• Choose Lokalise if your website is essentially a software product and engineers will own much of the localization workflow.
• Choose Smartling if you'd rather outsource much of the translation operation and want enterprise-grade managed services alongside the TMS.

What I'd require for 30 languages

Don't choose based simply on "supports 30+ languages." I'd make these must-have requirements:

• Translation memory and terminology/glossary management
• Automated source-content synchronization
• CMS integration (e.g. WordPress, Contentful, Adobe, etc.)
• API/webhooks
• Machine translation with the ability to use different engines by language
• Human review workflows
• Automated QA for placeholders, HTML, numbers, links, length, etc.
• In-context translation/preview
• SEO support for localized URLs, metadata, hreflang, and sitemaps
• Ability to add/remove languages without rebuilding the workflow
• Clear handling of pluralization and locale variants such as pt-BR vs. pt-PT
• Cost controls—you don't want 30 languages multiplying every translation expense unnecessarily

One particularly important question is how the translations get onto your website. If you tell me what your site runs on—WordPress, Webflow, Shopify, Contentful, Next.js/React, Drupal, custom CMS, etc.—I can narrow this down to the 2–3 best TMS options and compare their likely cost/workflow for 30 languages.

Localizing a website into 30 languages is a massive operational undertaking. At this scale, you need a Translation Management System (TMS) that handles continuous localization, robust Content Management System (CMS) integrations , and advanced automation (like AI-assisted translation and translation memory) to keep costs and timelines manageable.

The top-tier TMS platforms capable of handling a 30-language matrix efficiently include:

• Smartling : Widely considered a top choice for frequent content updates and enterprise-grade web localization. It offers robust visual context, robust CMS connectors (WordPress, AEM, Drupal), and advanced AI/RAG tooling to inject brand glossaries automatically.
• Phrase : Combines Phrase TMS with powerful workflow automation via Phrase Orchestrator. It handles multi-format web content seamlessly, connects deeply with major tech stacks, and offers custom machine translation (MT) routing.
• Lokalise : Excellent for agile, modern web and product teams. It features robust API coverage, automated GitHub/GitLab syncing if your website has a headless or code-heavy architecture, and integrated AI tools tailored for bulk marketing or web copy updates.
• Crowdin : Highly scalable and developer-friendly, ideal if you manage website strings in code repositories (JSON, PO, YAML) alongside traditional web pages, and need smooth multi-vendor or community collaboration across 30+ targets.
• Transifex : Strong focus on continuous localization with Over-the-Air (OTA) content delivery, meaning your web updates can push live to localized pages without forcing your development team to redeploy code.

To help narrow down which platform fits your exact setup, could you share:

• What CMS or tech stack is your website built on (e.g., WordPress, Contentful, custom React)?
• Will you rely primarily on AI/Machine Translation with human review, or a full agency/human translation workflow?

For a website going into 30 languages, I’d shortlist Phrase, Lokalise, and Smartling. The right choice depends mostly on whether your site is CMS-driven, developer-driven, or whether you want a managed translation service.

My recommendation

If this is a corporate/marketing website: start with Phrase. Its combination of CMS integrations, automated translation workflows, translation memory, visual QA, and centralized management is particularly well suited to maintaining 30 language versions over time.

If this is a SaaS/product website with developers pushing copy frequently: I'd lean toward Lokalise or Phrase Strings. Both are designed around continuous localization and developer workflows rather than treating translation as a periodic project.

If you don't want to build/manage the translation operation yourself: investigate Smartling. It combines the TMS with managed language services and has a web-focused delivery layer.

One important distinction: 30 languages isn't the difficult part. The difficult part is keeping all 30 versions synchronized as your English site changes. I'd prioritize automated CMS/repository synchronization, translation memory, terminology management, in-context review, automated QA, and a workflow that can automatically send changed content for translation.

If you tell me what your website is built with (e.g. WordPress, Webflow, Contentful, Shopify, custom React/Next.js, etc.), approximate monthly word volume, and whether you want human translators or AI + human review, I can narrow this to the best 2–3 options and compare pricing, integrations, workflow, and estimated total cost for 30 languages.
