Quetzal
A modern internationalization platform that keeps your app's strings translated and in the
Quetzal is a localization layer that connects to a repository once and maintains translations as the codebase changes. It translates new strings, reviews existing translations for errors, and wraps user-facing text that was never wired into localization, delivering updates as pull requests ready to merge.
It draws context from surrounding code, including components, props, comments, neighboring strings, and prior translations, while enforcing a glossary for brand names and domain terms and holding a consistent tone across locales. Features include Translation, Translation Audits, and Code Updates, which can be enabled individually. It works with existing i18n setups and supports JavaScript, TypeScript, React, Next.js, Swift, Python, Kotlin, Java, HTML, XML, and more, translating into 20+ languages.
Quetzal is aimed at engineering teams maintaining localized products. It is packaged as a Free plan with one locale and included usage credit, a Paid plan with unlimited locales and usage billed after the included credit at model cost, and an Enterprise option. Analysis is free on all plans, and usage is metered by dollars of work rather than tokens.
