LibreTranslate
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.
API Examples
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!"
}
Install and Run
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:
pip install libretranslate
libretranslate [args]
Then open a web browser to http://localhost:5000
Build and Run
If you want to make some changes to the code, you can build from source, and run the API:
git clone https://github.com/uav4geo/LibreTranslate
cd LibreTranslate
pip install -e .
libretranslate [args]
Then open a web browser to http://localhost:5000
Run with Docker
Simply run:
docker run -ti --rm -p 5000:5000 libretranslate/libretranslate
Then open a web browser to http://localhost:5000
Build with Docker
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.ymlfile to adapt it to your deployment needs, or use an extradocker-compose.prod.ymlfile for your deployment configuration.
