Free and Open Source Machine Translation API, entirely self-hosted. Unlike other APIs, it doesn't rely on proprietary providers such as Google or Azure to perform translations.
Request:
const res = await fetch("https://libretranslate.com/translate", {
method: "POST",
body: JSON.stringify({
q: "Hello!",
source: "en",
target: "es"
}),
headers: {
"Content-Type": "application/json"}
});
console.log(await res.json());
Response:
{
"translatedText": "¡Hola!"
}
You can run your own API server in just a few lines of setup!
Make sure you have installed Python (3.8 or higher), then simply issue:
git clone https://github.com/uav4geo/LibreTranslate --recurse-submodules
cd LibreTranslate
pip install -r requirements.txt
python main.py [args]
Then open a web browser to http://localhost:5000
Simply run:
docker run -ti --rm -p 5000:5000 libretranslate/libretranslate
Then open a web browser to http://localhost:5000
Make sure you cloned the models
submodule before building the Docker image:
docker build -t libretranslate .
Run the built image:
docker run -it -p 5000:5000 libretranslate [args]
Or build and run using docker-compose
:
docker-compose up -d --build
Feel free to change the
docker-compose.yml
file to adapt it to your deployment needs, or use an extradocker-compose.prod.yml
file for your deployment configuration.

The API on libretranslate.com should be used for testing, personal or infrequent use. If you're going to run an application in production, please get in touch to discuss options.
This work is largely possible thanks to Argos Translate, which powers the translation engine.
