I've been using openwebui and am pretty happy with it. Why do you like lm studio more?
LM Studio isn't FOSS though.
I did enjoy hooking up OpenWebUI to Firefox's experimental AI Chatbot. (browser.ml.chat.hideLocalhost to false, browser.ml.chat.provider to localhost:${openwebui-port})
Of course, for folks used to terminals, daemons and so on it makes sense from the get go, but for others it seemingly doesn't, and it doesn't help that Ollama refuses to communicate what people should understand before trying to use it.
