Locize vs. Tolgee:Managed vs. Self-Hosted

Tolgee is a modern, open-source alternative.
But choosing Tolgee often means choosing a new job: Infrastructure Management.
Locize is the Managed Evolution for teams that want to ship, not maintain.

The "Maintenance Tax"

Tolgee's self-hosted version is "free," but it comes with a hidden cost: your developers' time.

dns Tolgee
  • You manage the database & backups
  • You handle security patches & updates
  • You build your own global distribution
cloud_done Locize
  • We handle the high-availability DB
  • Global Edge CDN included out of the box
  • Zero-DevOps: We scale, you code
  • Flexible pricing: usage-based or fixed plans available

speedCDN-First Architecture

Your users care about loading speed. Locize serves translations from a global edge CDN with versioned delivery, per-namespace endpoints, and stale-while-revalidate caching — your translations load in milliseconds, worldwide.

dns Tolgee
  • Translations served from a single database
  • Publish-to-S3/Azure is an enterprise-only add-on
  • No built-in download analytics
cloud_done Locize
  • Global edge CDN (BunnyCDN + CloudFront) on every plan
  • Versioned delivery — publish to "latest", "production", etc.
  • Download analytics: see which apps consume your translations
  • Automatic backups with one-click restore

extensionThe i18next Ecosystem

Locize is built by the creators of i18next — the industry standard with 40+ maintained packages, 9+ framework integrations (React, Next.js, Angular, Vue, Svelte, Solid, etc.), and a 10+ year ecosystem.

dns Tolgee
  • Proprietary SDKs for React, Vue, Angular, Svelte
  • An i18next bridge (@tolgee/i18next) for existing i18next users
  • No control over the i18next ecosystem roadmap
cloud_done Locize
  • Native i18next support — we maintain the library
  • 40+ packages: backends, plugins, post-processors, language detectors
  • Drop-in localization via locizify — no code changes needed
  • Lightweight CDN client (locizer) for any framework

translatei18n Format Awareness

Different i18n frameworks handle plurals, context, and nesting differently. Locize's CAT editor natively understands these rules — it doesn't just store your translations, it knows how your framework interprets them.

dns Tolgee
  • Import/export in many file formats
  • Editor treats translations as raw text
cloud_done Locize
  • multiple i18n framework formats understood natively in the editor: i18next v3/v4, Vue i18n, ICU MessageFormat, Fluent, Polyglot, i18n-js, Android, and more
  • Framework-aware plural editing, context handling, and nesting
  • various file formats for import/export (JSON, XLIFF, YAML, Android, iOS, RESX, Gettext, etc.)

auto_awesomeAI Translation Infrastructure

Both platforms offer AI-powered translation. The difference: Locize injects your styleguide, glossary, and translation memory into every AI prompt automatically — so AI translations match your brand voice.

dns Tolgee
  • 5 LLM providers (enterprise-only, centrally managed)
  • 6 built-in MT providers
  • AI playground to test prompts (enterprise-only)
  • No styleguide-aware AI
cloud_done Locize
  • 5 AI providers: Locize AI, OpenAI, Gemini, Mistral, Lara (BYOK — you control the key)
  • 5 MT providers: Locize MT, DeepL, Google Translate, MyMemory, Lara
  • Styleguide-aware AI: tone, formality, and terminology rules injected into every AI prompt
  • AI assistant in the CAT editor for rephrasing, shortening, and generating variants

smart_toyAI Agent Integration (MCP)

Both platforms offer MCP servers for AI coding assistants. Locize's is more comprehensive.

dns Tolgee
  • 11 MCP tools (keys, translations, languages, branches)
  • Built into the self-hosted server
cloud_done Locize
  • 22 MCP tools — the full workflow: translations, versions, branches, tenants, languages, namespaces, publish, and more
  • Works with Claude, Cursor, VS Code, and any MCP client
  • MCP setup guide →

record_voice_overProfessional Translation Services

When you need human translators, Locize lets you order directly from the editor — no emails, no spreadsheets.

dns Tolgee
  • Generic "order translation" feature (enterprise-only)
  • Single agency integration
cloud_done Locize
  • 4 integrated translation services: BLEND, TextMaster, Supertext, Translated.com
  • In-app ordering with pricing quotes, fuzzy match exclusion, and order tracking

apartmentMulti-Tenancy

Building a white-label product? Locize lets you create tenant projects that inherit translations from a parent, with per-tenant overrides.

dns Tolgee
  • No multi-tenancy support
cloud_done Locize

account_treeVersioning & Branching

Both platforms offer branching. Locize additionally offers explicit version management that maps to your software releases.

dns Tolgee
  • Git-like branching with merge and conflict resolution (enterprise-only)
  • No separate version concept
cloud_done Locize
  • Branches for parallel translation workflows
  • Explicit versions (v1.0, v2.0) with publish, copy, and CDN delivery per version
  • Ship translations with your release cycles

securityEnterprise Security

dns Tolgee
  • TOTP-based two-factor authentication
  • SSO/SAML (enterprise-only)
  • Role-based access control
cloud_done Locize
  • Three MFA methods: TOTP, WebAuthn (FIDO2 hardware keys), and YubiKey
  • SSO via SAML 2.0 with multi-provider support
  • Role-based permissions per project, version, language, and namespace
  • Audit trail of all actions
  • Security details →

monitoringAnalytics & Monitoring

dns Tolgee
  • Translation progress dashboard
  • Activity log
cloud_done Locize
  • Health metrics with trend charts: translation completeness, new keys, fuzzy entries over time
  • Developer metrics: API calls, downloads by referrer, error rates
  • Cost forecasting and billed usage breakdown
  • Budget alerts when usage approaches limits
  • Unused key detection via locize-lastused — find and remove translations nobody sees
