Localization engineering platform where teams create persistent translation engines with glossaries, brand voice, and per-locale model preferences.
Lingo.dev is a localization infrastructure platform where engineering teams build stateful translation APIs called localization engines, configured with glossaries, brand voice rules, per-locale model chains, and quality scoring. Each engine uses retrieval-augmented localization to persist domain context across every request, reducing terminology drift and ensuring consistency. The platform integrates via API, CLI, CI/CD pipelines, and other integrations, and includes optional human review by qualified translators with MQM-based quality evaluation. Lingo.dev has powered over 200 million translated words for teams including Mistral, Solana, SoSafe, and Cal.com. Lingo.dev is a product of Lingo.dev.
