Locize

Locize is the localization and translation management platform built and run for over 10 years by the maintainers of i18next, one of the most widely used JavaScript internationalization frameworks.

FOR DEVELOPERS Stop shuffling translation files. New source strings flow into Locize automatically - directly from code (saveMissing), via CLI in CI/CD, through the API, or by importing XLIFF, Android, iOS String Catalogs, gettext, RESX, CSV, YAML and more. Namespaces and versions map naturally to your release process, and branches let you localize feature work in isolation.

FOR TRANSLATORS AND PRODUCT OWNERS Everyone works in the same collaborative editor: translation memory, glossary and style guide keep wording consistent; screenshots and segment context show where a text lives; the in-context editor lets non-developers edit translations directly on the live website. Comments, history and progress tracking are built in.

MACHINE TRANSLATION AND AI, GOVERNED Bring your own MT/AI provider or use the built-in ones. Every translation permanently stores its origin (human, machine or AI), AI output is quality-scored automatically, and low-confidence translations can be routed through a human review workflow before they are published. Nothing machine-made hides among human work.

INSTANT DELIVERY Approved translations publish to a global CDN and reach your users immediately - no redeploy, no app-store release. Versioning, per-segment history and automatic backups (with self-serve restore) keep every change auditable and reversible.

ENTERPRISE-READY Organizations hold the team and the billing: invite once at the organization and members inherit into every project, with per-project override or block, while external translators stay on the single project they work on. SSO (SAML) is configured once and charged once per subscription, 2-factor authentication can be enforced organization-wide, and admins can download an audit log of member and invitation changes. Multi-project setups for agencies (tenants), EU-based data storage and encryption in transit and at rest.

PRICING A free plan, then fixed monthly plans from $7 to $199 per project, each including a monthly word volume and unlimited edits. Beyond the included volume pricing stays usage-based, just stepped: extra capacity comes in packs of 10,000 words for $5, with optional auto-adapt so a release is never blocked. All projects of an organization share one invoice. Every account starts with a 14-day full-feature trial - no credit card required.
