Crowdin has been the default choice for translation management for years. It's mature, feature-rich, and most localization engineers have used it at some point. Better i18n is newer, built specifically for teams deploying modern web and mobile apps.
This is an honest comparison. We're biased — obviously — but we've tried to give Crowdin credit where it's genuinely stronger, and to explain clearly where we think Better i18n is the better choice for the specific problems modern app teams face.

Where Crowdin Wins
Enterprise translation workflows Crowdin has 15 years of enterprise translation workflow features — translation memories with granular control, advanced glossary management, QA automation, in-context translation for complex legacy systems, and a large marketplace of pre-built integrations. If you're managing hundreds of thousands of words across multiple products with a professional translation team, Crowdin's workflow tooling is genuinely more mature.
Translator marketplace Crowdin's marketplace connects you with vetted professional translators through the platform. If you need managed translation services rather than managing your own translators or using AI, this is a meaningful advantage.
Legacy integration ecosystem Crowdin has integrations with almost every major tool — Figma, GitHub, GitLab, Bitbucket, Jira, Confluence, Zendesk, Intercom, and dozens more. Many of these are mature and battle-tested.
On-premise option Crowdin offers an on-premise deployment for teams with strict data residency requirements. Better i18n is cloud-only (though translation data is served from Cloudflare's global CDN).
Where Better i18n Wins
CDN-first translation delivery
This is the biggest architectural difference. In Crowdin, your translation workflow ends with files. You download them, bundle them with your app, and deploy. When you update translations, you redeploy.
Better i18n delivers translations from a global CDN at runtime. Your app fetches translations from the CDN on load — no rebuild required to push translation updates live. This means:
- Fix a translation mistake without deploying code
- Ship translations to production minutes after they're approved
- Scale translation delivery globally without adding infrastructure
SDK-native integration
Better i18n provides first-party SDKs for every major framework: @better-i18n/next, @better-i18n/remix, @better-i18n/core, @better-i18n/expo, and native Swift and Flutter SDKs.
These aren't thin wrappers — they handle SSR, hydration, locale detection, CDN delivery, and fallback strategies out of the box. With Crowdin, you manage your own i18n library and Crowdin manages the translation files. Better i18n handles both layers.
MCP (Model Context Protocol) support
Better i18n has native MCP support via @better-i18n/mcp. AI assistants like Claude can manage your translations directly — adding keys, updating translations, checking for missing translations, and publishing — all through natural language in your AI coding environment.
Crowdin has no MCP support. If you're using AI-assisted development and want your AI assistant to help manage localization alongside your code, Better i18n is currently the only option.
Content CMS for marketing and rich content
Better i18n includes a Content CMS that handles localization of rich content — blog posts, feature pages, email templates, pricing data. Crowdin is a translation management system; it handles strings. Better i18n handles strings and structured content in one platform.
AI translation quality and control
Better i18n has native AI translation with multi-engine support. Crowdin's AI translation is available via integrations with third-party MT providers, which adds cost and complexity.
Pricing transparency
Crowdin's pricing is not publicly disclosed at the enterprise tier, and teams often report unexpected costs at scale. Better i18n has transparent, per-tier pricing visible at better-i18n.com/pricing. The free tier is genuinely usable — not a crippled trial.
Head-to-Head: Specific Scenarios
Scenario 1: Next.js app, CI/CD on GitHub, deploying to Vercel
Better i18n: Install @better-i18n/next, connect GitHub repo, configure sync. Translations are delivered from CDN — no bundle size impact. When a translator approves a translation, it's live in 60 seconds without a deploy.
Crowdin: Set up GitHub integration, configure your next-intl setup to consume Crowdin output, build translation bundles into your deployment. Translation updates require a new deploy.
Winner: Better i18n for CDN delivery and integrated SDK.
Scenario 2: React Native / Expo app
Better i18n: @better-i18n/expo with native AsyncStorage caching, CDN delivery, two-phase load (cache-first, then refresh). Works offline with cached translations.
Crowdin: GitHub integration exports string files, which you bundle into your app at build time. OTA updates of translation strings require a code push or new app release.
Winner: Better i18n for CDN delivery without requiring app releases.
Scenario 3: Enterprise team, 50+ languages, professional translators
Crowdin: Translation memory that saves every previously translated segment, advanced glossary management, in-context translation editor, QA automation, vendor management.
Better i18n: Translation memory, glossary, GitHub sync, AI translation. Review workflow is simpler than Crowdin's.
Winner: Crowdin for professional translation workflow maturity at scale.
Scenario 4: AI-assisted development with Claude
Better i18n: Native MCP server. Your AI assistant can list keys, propose translations, add new keys, and publish — in natural language.
Crowdin: No MCP support.
Winner: Better i18n.
Scenario 5: Marketing site localization alongside app strings
Better i18n: Unified platform — app strings, marketing pages, blog posts, email templates all in one dashboard.
Crowdin: Translation management for strings only. Rich content requires a separate CMS integration.
Winner: Better i18n.
Migration from Crowdin to Better i18n
- Export your translation files from Crowdin (JSON, YAML, PO, whatever format you use)
- Import into Better i18n via the CLI:
better-i18n import --format json ./translations - Install the Better i18n SDK for your framework
- Connect GitHub for ongoing sync
- Test — CDN delivery means no build changes needed to validate translations
Most teams complete migration in a day for simple setups, or a few days for complex setups with many languages and custom file formats.

Choose Crowdin if:
- You have a professional translation team with complex workflow requirements
- You need on-premise deployment
- You're managing 50+ languages with professional translators who use in-context editors

Choose Better i18n if:
- You're building a modern web or mobile app and want CDN-first translation delivery
- You want your translations and your code to move at the same speed (no redeploy required)
- You're using AI-assisted development and want localization integrated into that workflow
- You need to localize both your app strings and your content (marketing, emails, help center) in one platform
- You want a generous free tier to get started without budget approval
