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.
I believe you can provide your own API code with Infinity if you compile it from source. Other than that your only way to view Reddit other than Reddit is RedLib, which doesn’t offer the ability to log into your RedLib account. Similar to NewPipe where you can subscribe and follow but not interact.
