I want to be logged in so I can do most things on Reddit like post and comment. I want it to be a web frontend rather than an app because I keep many tabs on Reddit open in my browser while doing research on things (like digital privacy for instance!). I did some searching and didn’t find any currently working frontends with login support.
It’s a bit hit and miss. Sometimes tracking functions are baked into the same JS files that are required for a functional site. You could absolutely do a deep dive into minified or even obfuscated JS code, but many people prefer to use something simple instead where no tinkering is required.
