Locize alternative: AZbox vs Locize

AZbox vs Locize: An Honest Comparison

Locize is built by the people behind i18next. If your project already runs on i18next, nothing integrates with it more deeply — that is a genuine advantage and worth weighing seriously. AZbox takes a narrower target: teams that already have to deliver in several languages on a recurring basis, and whose real cost is keeping those strings correct as the product changes.

Where AZbox Fits Better

• You ship in several languages on a recurring basis — the work is not the first translation, it is every release after it.
• You need to fix strings in apps already published — over-the-air updates replace text in a shipped app without another store review, through the Dart SDK or the REST API.
• You run several client projects at once — a project per client, each with its own languages and members, unlimited from the Starter plan up.

Where Locize Fits Better

• Your project is built on i18next — it is made by the same people. That closeness is hard to beat.
• You want granular pay-as-you-go — their model bills by usage rather than by tiers.
• You need their CDN specifically — a mature delivery layer with years behind it.

The Bottom Line

Pick AZbox if the recurring cost of staying translated is your problem. Pick Locize if you need what it does better than us — the section above is not a formality.
