About

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.

Lingo.dev is a localization engineering platform that lets teams configure and persist glossaries, brand voice, and per-locale model chains, then call them from code, CLI, CI/CD, or MCP to keep terminology consistent across releases.

Create a localization engine that stores glossary, brand voice, and per-locale model chains. Call the engine via backend code, CLI, CI/CD, or MCP to localize content with context attached. The platform supports context enrichment, glossary-based retrieval, model chaining with provider fallbacks, and an end-to-end pipeline including pre-processing, context enrichment, translation, optional human post-editing, post-review, and delivery via webhooks or WebSocket. It emphasizes terminology lock, per-locale tone, and automated, measurable quality across releases.

Who it’s for: Engineering teams and product teams responsible for localization within software products, including those needing terminology control and per-locale model customization.
