It would be good to share other OSS alternatives here, some alternatives I've seen mentioned in Reddit threads:
   - jan.ai
   - librechat.ai
   - AnythingLLMWitsy is very good.

They don't really do a good job describing the features, but you can use it for any OpenAI compatible local API as well (llama.cpp, koboldcpp, etc).

I'm leaning towards this one myself but I'm still early in researching alternatives.
