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.
A localization engine is a stateful translation API that holds your glossary, brand voice, and model chain. Every request enters the product with that context already attached, ensuring consistent terminology and measurable quality over time.
Lingo.dev enables professional localization infrastructure delivered as code, with retrieval-augmented translation, automated quality scoring, and human review when needed. It integrates directly into developer workflows via API, CLI, GitHub Action, and React MCP.
