In their own words
locize
Locize is a localization platform for connecting software code and internationalization setups with translators, then delivering translation updates through a CDN or API without a full app redeploy. Developers can sync keys and source strings through CLI or CI, while translators and reviewers use a separate interface with translation memory, in-context editing, review workflows, and machine or generative AI translations. Listed integrations and support include i18next, React, Vue, Angular, Next.js, Node.js, Figma, iOS and Android, plus PHP, Python, Java, and.NET. The Free plan is free and includes one user, two languages, five namespaces, and 100K standard CDN downloads per month. Starter costs $7 a month, and a 14-day trial is listed. Download limits matter: fixed plans block a project after standard CDN use exceeds 110% of its allowance, while Free automatically unpublishes translations. Locize lists MFA options, SAML 2.0 SSO, role-based permissions, backups, encryption, and Swiss FADP and EU GDPR coverage.
