Selectiecriteria
Waar je in 2026 op moet letten bij een TMS
Developer-workflow
CLI voor key-scanning en synchronisatie, GitHub Actions-integratie en type-veilige SDK's. Een TMS die integreert met code review voorkomt de opeenhoping van vertaalschuld.
AI-vertaalkwaliteit
Contextbewuste AI (niet alleen Google Translate) die je productterminologie begrijpt, de merkstem behoudt en terminologieglossaria ondersteunt. Zoek naar workflows met menselijke review, niet volledig geautomatiseerde publicatie.
CDN-levering
Vertalingen worden vanaf de edge geleverd — niet gebundeld in je JavaScript. Snelle cold-start en directe OTA-updates zijn alleen mogelijk met CDN-first levering. Belangrijk voor mobiele apps en SPA's.
Prijstransparantie
Wees voorzichtig met platforms die per woord, per taal of per seat kosten in rekening brengen, waardoor kosten onvoorspelbaar worden op schaal. Geef de voorkeur aan platforms met vaste prijzen of genereuze gratis plannen om te beginnen.
MCP- en AI-agentondersteuning
In 2026 schrijven AI-agents code en beheren ze content. Een TMS met MCP-ondersteuning (Model Context Protocol) stelt AI-agents in staat om keys te vertalen, content te beoordelen en wijzigingen rechtstreeks te publiceren — wat handmatige overhead aanzienlijk vermindert.
Migratiekosten
Van TMS wisselen is pijnlijk. Controleer of het platform import ondersteunt vanuit je huidige formaat (JSON-, XLIFF-, PO-bestanden), een duidelijke migratiegids heeft en je niet vastzet met eigen formaten.
Frequently Asked Questions
What is a Translation Management System (TMS)?
A Translation Management System (TMS) is a platform that centralizes and automates the process of translating software, websites, and digital content. A TMS stores all your translation keys, manages the workflow between developers and translators, integrates AI translation, and delivers the final translations to your app. Modern TMS platforms also integrate with Git, CDNs, and CI/CD pipelines — making localization a continuous process rather than a manual export-import cycle.
What is the difference between a TMS and a CAT tool?
A CAT (Computer-Assisted Translation) tool is a translator's workbench — it shows source and target side-by-side, suggests translations from memory (translation memory / TM), and enforces quality checks. A TMS manages the broader workflow: project management, file routing, vendor management, and integration with code repositories. Many modern platforms combine both: Better I18N, Lokalise, and Phrase include CAT-like translation editors alongside TMS workflow features.
How much does a TMS cost?
Pricing varies enormously. Phrase starts at ~$1,245/month, Lokalise at ~$140/month, and Crowdin at ~$40/month for basic plans. Better I18N offers a free tier for getting started and paid plans based on project scale. Enterprise platforms like Smartling and XTM are priced on request and can cost thousands per month. The key is to evaluate total cost: platform fees plus the time saved by developers and translators.
Can a TMS replace human translators?
Not entirely — but it dramatically reduces their workload. AI translation (including GPT-4 and specialized MT engines) produces good first drafts that human translators then review and correct. This post-editing workflow is typically 3-5x faster than translating from scratch. For high-stakes content (legal, medical, marketing copy), human review remains essential. For UI strings and error messages, AI translation with spot-checking is usually sufficient.
What makes Better I18N different from Crowdin, Lokalise, and Phrase?
Better I18N is built for the modern development stack: CDN-first delivery means translations never ship in your JavaScript bundle, MCP support lets AI agents manage translations directly, and the Git-native workflow treats translations as first-class code artifacts. Crowdin and Lokalise are excellent products but were designed in the 2010s — Better I18N is designed for the 2020s, with AI agents, edge computing, and developer experience as first-class concerns. Plus, Better I18N starts free.
How do I migrate from Crowdin or Lokalise to Better I18N?
Better I18N's CLI can import existing translation files in JSON, XLIFF, PO, and ARB formats. The migration steps are: export your translations from Crowdin/Lokalise, run `better-i18n import` to push them to your Better I18N project, configure your SDK to point to the Better I18N CDN, and remove the old TMS integration. Most teams complete the migration in under a day. Better I18N's support team can assist with complex migrations.
