Mastodon Content Translation

In Mastodon, you can enable content translation using a DeepL or LibreTranslate backend. This means you need an API key from one of those services.

Once you have an API key, you can email to request that your API key be added to your server configuration.

For DeepL, include your API key and if the key is from a free or paid plan.

For LibreTranslate, include your API key and the LibreTranslate endpoint.

You can get a free or paid DeepL API key at

You can also run your LibreTranslate server and use it as your translation backend for Mastodon. You can read more about running your own LibreTranslate server at
