I want to make a request from my website to my own server, the server would further request a third party website, it would run the website through an extension (as if the request was made by you on a browser with an extension) and other various content filters, maybe even rendering the website on the server, before serving it and rendering it on my website.

Since this is for Safari on iOS the extension and filtering must happen on the server and client side is not possible, I think I could do this with Python and Selenium but seems like a very bad way of doing it. It will be only for personal use so I am not worried about any external issues.

Is this at all feasible and if yes I would appreciate some pointers in the right direction
