Everything your localization workflow needs. None of what it doesn't.
Diff-first, sync-first architecture: no busy-work for translators, no locale drift for developers.
Built for the way product teams actually ship
String auto-detection
Every push is scanned for new, changed, and deleted string keys. Nothing is queued that hasn't changed: no noise for your translators.
Branch-isolated locales
Feature branches get their own locale state. Translation work on a branch never reaches main until the branch merges.
Diff-only translator view
Translators work in a focused diff view: old value on the left, new source on the right, translation field below. No full-file exports.
Webhooks and API access
Trigger custom workflows when strings change, when translations are approved, or when a sync completes. Full REST API available on Studio and Scale.
Team roles and review gates
Scale plan supports role-based access: translators, reviewers, and admins. Reviews are required before any translation merges to a protected branch.
Sync status API
Query the sync state of any string key or locale at any commit SHA. Build your own dashboards or pipe sync status into your CI pipeline.
