The localization engineering platform.

Teams configure localization engines that persist glossaries, brand voice, and per-locale model chains—then call them from backend code, CLI, CI/CD, or MCP. Terminology stays consistent across every locale, every release.

Key Features

  • Stateful Translation API: Create, configure, and call localization engines with persistent domain context.
  • Glossary Enforcement: Maintain consistent product terminology across all locales.
  • Brand Voice Configuration: Define tone and formality per locale.
  • Model Chain Management: Ranked providers with automatic fallback for reliability.
  • AI Reviewers: Independent scorers for quality dimensions (e.g., accuracy, fluency).
  • Retrieval-Augmented Localization: Re-localize only what changed while retrieving matching context.
  • Multi-Channel Integration: Call from code, CLI, CI/CD pipelines, or MCP.
  • Terminology Tracking: Measure and audit quality over time to prevent drift.

Tech / Self-Hosting

Lingo.dev is a cloud-native SaaS platform with no self-hosting option. The service is built for scalability and integrates seamlessly with existing development workflows. API access is provided via REST endpoints with SDKs for popular languages. The platform is designed for teams prioritizing developer experience and infrastructure reliability.
