also would be nice to know which of those have proxy (not direct to provider)

some of the chatbots send data to intermediate servers and then route the request to the LLM provider.
This is very important in terms of data security and privacy.

Also some might be using connection directly from the FrontEnd (with now proxy) so also should be noted

Unfortunately it's impossible to know this with the non-open-source apps - if you have info on each app feel free to open a pull request!
