LibreTranslate is a Free and Open Source Machine Translation API. Unlike other APIs, it doesn’t rely on proprietary providers such as Google or Azure to perform translations. Instead, its translation engine is powered by the open source Argos Translate library.

Quickstart

Self-Hosted

If you want to run LibreTranslate for free on your machine:

$ pip install libretranslate
$ libretranslate
$ curl -X POST http://localhost:5000/translate -d q="Hello" -d source=en -d target=es

{"translatedText":"Hola"}

Managed Hosting

If you’d like an easier setup, high availability, fast translations and a professionally managed service for a small monthly cost:

Get an API key from: https://portal.libretranslate.com

$ curl -X POST https://libretranslate.com/translate -d q="Hello" -d source=en -d target=es -d api_key=xxxxx

{"translatedText":"Hola"}

Either way we’re happy you’re here! ❤
