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
