@skydotbit Like I legitimately cant think of a reason to ban a key for translating anything. It's text. It's not an image. Deepl isn't going to get into legal trouble for translating text.
I don't want to devote too much hardware to the service, but I can definitely throw one up on a orange pi 5 plus. It has 32GB RAM, so it should be able to handle it. The only problem would be CPU usage. It has a NPU, but I dont think libretranslate can use the NPU.
