Lingo.dev

Lingo.dev is a localization engineering platform where teams create localization engines – stateful translation APIs configured with glossaries, brand voice rules, per-locale model preferences, and quality scoring. Each engine persists domain context across every request via retrieval augmented localization (RAL). Integrate via API, CLI, CI/CD, or other integrations. Localization infrastructure behind 200M+ translated words for teams including Mistral, Solana, SoSafe, and Cal.com.
