Self hosting would be ideal, but I’m not sure what URL to provide. Can I do it through my Umbrel somehow?
Discussion
I’ve never used Umbrel but I don’t think there’s any first-party LibreTranslate integration with Umbrel. If I understand correctly, Umbrel is just a layer running on top of Linux, so if it allows you to run Docker and run arbitrary command line commands, you could just build LibreTranslate with Docker by following the README: https://github.com/LibreTranslate/LibreTranslate
You might need an Umbrel expert to help you through some of the steps though, especially with figuring out which URL and port to use.
