Lingarr is a subtitle translation application that combines multiple translation services to automatically translate subtitle files to a target language. It supports LibreTranslate, local AI, and cloud providers like DeepL, Anthropic, OpenAI, and more, and can run as a local or SaaS deployment with a RESTful API for integration.
Key Features
- Supports multiple translation services including LibreTranslate, Local AI, DeepL, Anthropic, OpenAI, DeepSeek, Gemini, Google, Bing, Yandex and Azure.
- Local and SaaS deployment options with Docker Compose and Docker runtime support.
- Multi-architecture Docker images (amd64 and arm64) with deployment flexibility.
- Exposes a RESTful API for integration into other apps.
- Explicit setup guidance for running Lingarr via Docker and Docker Compose.
Use Cases
- Self-hosted media libraries: deploy Lingarr with Docker Compose to automatically translate and apply subtitles for movies and TV shows.
- Flexible translation workflows: choose from LibreTranslate, OpenAI, DeepL, or other providers to match cost, latency, and quality needs.
- API-driven integrations: use the RESTful API to incorporate Lingarr subtitle translation into custom media workflows or apps.
Limitations and Considerations
- Lingarr supports a variety of translation providers, which may have different terms of service, pricing, and data handling. (Implemented via the multi-provider approach described in the README.)
Conclusion
Lingarr provides a flexible, multi-provider subtitle translation solution that can run locally or as a SaaS service, with a RESTful API for programmatic control. Its Docker-based deployment and broad provider support make it adaptable to diverse translation needs in media workflows.
