DeepLX

DeepLX is an open-source project, not made by DeepL, that offers DeepL translation through a simple API. You use it through a DeepLX server: a public one, a hosted one you pay for, or one you run yourself.

DeepLX is unofficial and can stop working at any time. For something dependable, use the DeepL API.

Add it

1. On API Providers, click Add provider and choose DeepLX.
2. Enter the server’s address in URL. It’s the full address of the translate endpoint, for example:
   • http://127.0.0.1:1188/translate for a server on your own computer,
   • https://api.deeplx.org/{{apiKey}}/translate for a hosted service that puts your key in the address.
3. If the address contains {{apiKey}}, enter your key in API key; it takes that place in the address.
4. Click Test connection.

Good to know

• DeepLX can’t do translation-only mode. Use bilingual mode, or another provider for translation only.
• Public servers are often slow or rate-limited. If translations fail, lower Requests per second under Translation queue.
