Locize vs. Localazy:Ecosystem vs. Tool
Localazy is a capable generic TMS with a CDN layer. Locize is purpose-built infrastructure for the i18next ecosystem — not just a place to store translations, but the live runtime backend your app reads from.
Integration Depth: Adapter vs. Native Backend
Localazy connects to i18next through generic file sync. Locize is built by the i18next creators as the managed backend — the integration is fundamentally different.
- Generic TMS: Supports many frameworks via file sync — i18next is one of many.
- No namespace concept: No built-in support for i18next namespaces, branching, or versioning.
- No multi-tenant model: SaaS teams needing per-client overrides must use workarounds.
- CDN billed separately: CDN usage is an add-on on top of the subscription cost.
- Built by the i18next team: The dedicated
i18next-locize-backendplugin is first-party. - Namespaces, branches, versions: All built-in and designed around i18next conventions.
- Multi-tenant SaaS support: Per-tenant overrides served from the same CDN natively.
- CDN included: Standard downloads included in every fixed plan — overage is just $5/1M requests.
Pricing: Source Keys vs. Total Words
Each platform prices differently. Neither model is universally better — it depends on your project shape.
- Source-key pricing: Language-agnostic — adding more languages costs nothing extra.
- Unlimited seats: All plans including free include unlimited contributors.
- Lower entry price: For very small key counts the free and starter tiers can be cheaper.
- Total-word pricing: Scales with languages × words — predictable but grows with locale count.
- CDN included: No separate CDN billing — downloads are part of the fixed plan.
- Usage-based option: Pay only for what you use starting at $5/month — ideal for variable workloads.
- Review, glossary, etc. on lower tiers: No feature gating behind enterprise plans.
If your project has few source keys but many target languages, Localazy's model favors you. If you need CDN delivery, namespaces, branches, and deep i18next integration, Locize's total cost is typically lower once you factor in Localazy's CDN add-on and the integration work you skip.

Consider Localazy if…
- You have many target languages but few source keys and need language-agnostic pricing
- Unlimited contributor seats is a hard requirement on the free tier
- Your workflow is primarily file-based export/import and you do not need runtime CDN delivery included in the plan
Choose Locize if…
- You are using i18next and want a native backend — not a generic adapter
- You need CDN delivery included, with overage at $5/1M requests
- Your app requires namespaces, branches, or versioning
- You are building a SaaS product with per-tenant translation overrides
- You want your TMS subscription to directly support i18next open-source development
