Lingo.dev v1.0 introduces localization engines  stateful translation APIs that you configure once and call from backend code, MCP, or CI/CD. Before today, every team that wanted consistent terminology, on-brand tone, and per-locale rules wired it up by hand: a glossary in one repo, brand-voice notes in a Notion doc, prompt scaffolding hard-coded into the app. The engine collapses all of that into a single addressable thing.

What's in the launch

• Localization engines. Configure models, brand voice, instructions, and glossaries per locale.

• LLM models. Pick the model per locale, with ranked fallback chains for reliability.

• Brand voices. Linguistic rules and tone per locale.

• Instructions. Per-locale translation rules for specific patterns.

• Glossaries. Lock down product terminology across languages and builds.

• AI Reviewers. Cross-model evaluation criteria for translation quality.

• Playground. Test engine configurations before they go live.

• Reports. Word generations, token consumption, top locales, glossary coverage, change rates.
