LibreTranslate is a free and open source machine translation API that is fully self-hosted and offline capable, powered by the Argos Translate engine. It exposes a simple REST endpoint for translating text and files without relying on proprietary services like Google or Azure.
Use cases
- self-host a translation API without proprietary services
- translate text between languages offline
- add machine translation to an application via REST API
- translate documents and files programmatically
- detect the source language of text
- run a private translation server for privacy-sensitive content
When to choose
- you need translation without sending data to Google, Azure, or other proprietary APIs
- you want an offline or air-gapped translation solution
- you need a simple REST API you can self-host with pip or Docker
- privacy or data sovereignty rules prohibit third-party translation services
When to avoid
- you need the highest translation quality available from large commercial models
- you want a managed service without running your own infrastructure (though hosted API keys exist)
- you need very high throughput translation on limited hardware
- you need translation for rare language pairs not covered by Argos models
