|
|
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:
|
|
|
|
```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" }
|

|
|
```
|
|
|
|
Response:
|
|
|
|
```javascript
|
|
{
|
|

|
|
}
|
|
```
|
|
|
|
## 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 is recommended), then simply issue:
|
|
|
|
```bash
|
|
pip install libretranslate
|
|
libretranslate [args]
|
|
```
|
|
|
|
Then open a web browser to http://localhost:5000
|
|
|
|
If you're on Windows, we recommend you [Run with Docker](#run-with-docker) instead.
|
|
|
|
## 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]
|
|
|
|
# Or
|
|
python main.py [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
|
|
|
|
```bash
|
|
docker build [--build-arg with_models=true] -t libretranslate .
|
|
```
|
|
|
|
If you want to run the Docker image in a complete offline environment, you need to add the `--build-arg with_models=true` parameter. Then the language models get downloaded during the build process of the image. Otherwise these models get downloaded on the first run of the image/container.
|
|
|
|
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.

|
|
|
|
## Manage API Keys
|
|
|
|
LibreTranslate supports per-user limit quotas, e.g. you can issue API keys to users so that they can enjoy higher requests limits per minute (if you also set `--req-limit`). By default all users are rate-limited based on `--req-limit`, but passing an optional `api_key` parameter to the REST endpoints allows a user to enjoy higher request limits.
|
|
|
|
To use API keys simply start LibreTranslate with the `--api-keys` option.
|
|
|
|
### Add New Keys
|
|
|
|
To issue a new API key with 120 requests per minute limits:
|
|
|
|
```bash
|
|
ltmanage keys add 120
|
|
```
|
|
|
|
### Remove Keys
|
|
|
|
```bash
|
|
ltmanage keys remove <api-key>
|
|
```
|
|
|
|
### View Keys
|
|
|
|
```bash
|
|
ltmanage keys
|
|
```
|
|

## 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 get an API key or discuss other options.
|
|
|
|
### Can I use this behind a reverse proxy, like Apache2?
|
|
|
|
Yes, here is an example Apache2 config that redirects a subdomain (with HTTPS certificate) to LibreTranslate running on a docker at localhost.
|
|
```
|
|
sudo docker run -ti --rm -p 127.0.0.1:5000:5000 libretranslate/libretranslate
|
|
```
|
|
You can remove `127.0.0.1` on the above command if you want to be able to access it from `domain.tld:5000`, in addition to `subdomain.domain.tld` (this can be helpful to determine if there is an issue with Apache2 or the docker container).
|
|
|
|
Add `--restart unless-stopped` if you want this docker to start on boot, unless manually stopped.

|
|
|
|
Replace [YOUR_DOMAIN] with your full domain; for example, `translate.domain.tld` or `libretranslate.domain.tld`.
|
|
|
|
Remove `#` on the ErrorLog and CustomLog lines to log requests.
|
|
|
|
```ApacheConf
|
|
#Libretranslate
|
|
|
|
#Redirect http to https
|
|
<VirtualHost *:80>
|
|
ServerName http://[YOUR_DOMAIN]
|
|
Redirect / https://[YOUR_DOMAIN]
|
|
# ErrorLog ${APACHE_LOG_DIR}/error.log
|
|
# CustomLog ${APACHE_LOG_DIR}/tr-access.log combined
|
|
</VirtualHost>
|
|
|
|
#https
|
|
<VirtualHost *:443>
|
|
ServerName https://[YOUR_DOMAIN]
|
|
|
|
ProxyPass / http://127.0.0.1:5000/
|
|
ProxyPassReverse / http://127.0.0.1:5000/
|
|
|
|
SSLEngine on
|
|
SSLCertificateFile /etc/letsencrypt/live/[YOUR_DOMAIN]/fullchain.pem
|
|
SSLCertificateKeyFile /etc/letsencrypt/live/[YOUR_DOMAIN]/privkey.pem
|
|
SSLCertificateChainFile /etc/letsencrypt/live/[YOUR_DOMAIN]/fullchain.pem
|
|
|
|
# ErrorLog ${APACHE_LOG_DIR}/tr-error.log
|
|
# CustomLog ${APACHE_LOG_DIR}/tr-access.log combined
|
|
</VirtualHost>
|
|
```
|
|
|
|
Add this to an existing site config, or a new file in `/etc/apache2/sites-available/new-site.conf` and run `sudo a2ensite new-site.conf`.
|
|
|
|
To get a HTTPS subdomain certificate, install `certbot` (snap), run `sudo certbot certonly --manual --preferred-challenges dns` and enter your information (with `subdomain.domain.tld` as the domain). Add a DNS TXT record with your domain registrar when asked. This will save your certificate and key to `/etc/letsencrypt/live/{subdomain.domain.tld}/`. Alternatively, comment the SSL lines out if you don't want to use HTTPS.
