# LibreTranslate [Try it online!](https://libretranslate.com) | [API Docs](https://libretranslate.com/docs) [![Publish to DockerHub](https://github.com/uav4geo/LibreTranslate/workflows/Publish%20to%20DockerHub/badge.svg)](https://hub.docker.com/r/libretranslate/libretranslate) ![Publish to GitHub Container Registry](https://github.com/uav4geo/LibreTranslate/workflows/Publish%20to%20GitHub%20Container%20Registry/badge.svg) 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. ![image](https://user-images.githubusercontent.com/1951843/102724116-32a6df00-42db-11eb-8cc0-129ab39cdfb5.png) [Try it online!](https://libretranslate.com) | [API Docs](https://libretranslate.com/docs) ## API Examples Request: ```javascript 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: ```javascript { "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: ```bash 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: ```bash 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: ```bash 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: ```bash docker build -t libretranslate . ``` Run the built image: ```bash docker run -it -p 5000:5000 libretranslate [args] ``` Or build and run using `docker-compose`: ```bash docker-compose up -d --build ``` > Feel free to change the [`docker-compose.yml`](https://github.com/uav4geo/LibreTranslate/blob/main/docker-compose.yml) file to adapt it to your deployment needs, or use an extra `docker-compose.prod.yml` file for your deployment configuration. ## Arguments | Argument | Description | Default | | ------------- | ------------------------------ | -------------------- | | --host | Set host to bind the server to | `127.0.0.1` | | --port | Set port to bind the server to | `5000` | | --char-limit | Set character limit | `No limit` | | --req-limit | Set maximum number of requests per minute per client | `No limit` | | --batch-limit | Set maximum number of texts to translate in a batch request | `No limit` | | --ga-id | Enable Google Analytics on the API client page by providing an ID | `No tracking` | | --debug | Enable debug environment | `False` | | --ssl | Whether to enable SSL | `False` | | --frontend-language-source | Set frontend default language - source | `en` | | --frontend-language-target | Set frontend default language - target | `es` | | --frontend-timeout | Set frontend translation timeout | `500` | ## Roadmap Help us by opening a pull request! - [x] A docker image (thanks [@vemonet](https://github.com/vemonet) !) - [x] Auto-detect input language (thanks [@vemonet](https://github.com/vemonet) !) - [ ] User authentication / tokens - [ ] Language bindings for every computer language ## FAQ ### Can I use your API server at libretranslate.com for my application in production? 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](https://uav4geo.com/contact) to discuss options. ## Credits This work is largely possible thanks to [Argos Translate](https://github.com/argosopentech/argos-translate), which powers the translation engine. ## License [GNU Affero General Public License v3](https://www.gnu.org/licenses/agpl-3.0.en.html)
