LibreTranslate App

About

Free and Open Source Machine Translation API. Self-hosted, offline capable and easy to setup.

User Management

The app has no user management of it's own. By default, anyone (without a token) can make 30 requests per minute. You can change this in /app/data/env.sh.

Custom config

Custom environment variables can be set in /app/data/env.sh using the File manager.

API

By default, the API can be used without a key to make 30 requests per minute:

$ curl -d "q=cloudron%20ist%20wunderbar&source=de&target=en" -X POST https://translate.domain.com/translate

To lock the app and enforce use of a key, set LT_REQUIRE_API_KEY_ORIGIN=true in /app/data/env.sh

Create Key

Use the ltmanage command to create an API key. On Cloudron, LibreTranslate runs as the cloudron user. Run the following command using a Web Terminal to create an API with a limit of 120 requests per minute:

# su - cloudron -c 'ltmanage keys --api-keys-db-path /app/data/api_keys.db add 120'

The key can be used as follows:

$ curl -d "q=cloudron%20ist%20wunderbar&api_key=f67d5afe-aa14-4d37-90f7-f7d9636b721e&source=de&target=en" -X POST https://translate.domain.com/translate
