Build me a modern web proxy app with a clean, sleek interface and fast loading, like the one in this repo.

I want users to be able to open websites through the proxy, keep multiple sites open in tabs, and use it for common school or work browsing. Please include the features mentioned here, like about blank cloaking, tab cloaking, an inspect element style option, a good collection of apps and games, themes, Now.gg support, and Geforce NOW support. Make it easy to use, with simple menus and a polished home screen.

Also add optional password protection that can be turned on in config, and make sure it runs well as a normal web app that can be deployed on a server. If anything needs current docs or setup details, look them up online and use the best current approach.
