Localazy
SMBLocalization platform for apps and digital products with collaborative translation workflows.
In-place editor with screenshot context lets reviewers correct UI wording without switching to separate reference files.
Localazy’s core loop revolves around extracting resources, mapping them to locales, and letting reviewers edit translations directly in context through the web editor. The system tracks changes as source strings evolve, so teams can handle continuous localization without waiting for full batch jobs. Integrations cover syncing translation files to and from external repositories and tooling, which reduces manual exports when translations are produced by different partners.
A tradeoff appears in how Localazy’s workflow centers on its own editor and project states rather than acting like a thin pass-through for existing pipelines. Teams that already run a complex translation proxy setup or depend on custom string processing steps may need to adapt their l10n pipeline around Localazy’s model. Localazy fits best when teams want governance over what becomes publishable, while keeping translators focused on in-context changes.
- +In-context web editing ties translations to real screenshots
- +Project states support review and release gating per locale
