LibreChat or OpenWebUI ?

Hello, I have a friend that while technical, it doesn't know too much about AI, I've helped them with the infrastructure setting and that works like a charm, but he's interested in a thing that where I don't have too much experience with, and that is flashy chat "do everything" interfaces.

I did try the above mentioned program more than a year before and then I've lost interest as they don't produce any money. I've seen that they are maintained and from outside look nice, please help me select the "flashiest" and full of features one, together with gotchas if they are any, like "the image analyzer crashes if the image is larger than 1MB..."

Other options are also most welcome, but they have to be as colorful, byzantine and full of options as possible, no minimalist functional approach (my one HTML file that I use to chat with vLLLM driven models was rejected in disgust).

I do desperately try to keep them away form OpenClaw and its ilk, please help.
