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.
Because privacy frontends send only the required data without the whole tracking garbage to the corresponding platform. That doesn't end at API calls, they are missing JS trackers that track your mouse movement, how long you look at a page, etc as well.
Often, a nice side effect is that ads are removed as well.
Unfortunately, that doesn't exist without the API. You could use the normal frontend and container tabs for ff. They are an extension, but it's made by Mozilla and integrates quite well. You can even automate it so Reddit always opens in a specific container.
Very unlikely to exist. Libreddit (that didn't support user login to start with) was discontinued a while ago, and Reddit's hostile stance on 3rd party clients in general means any project gaining prominence will get killed before they become popular. RedReader (an Android app) is only permitted to use its API for free because of public outcry due to accessibility issues involving blind users. A web frontend with user login support for Reddit will get hunted down by Reddit's legal department if it ever reaches maturity.
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.
doesn't old reddit work well enough? they removed the login prompt but it can be restored pretty easily with a userscript (just inject the login prompt copied from the wayback machine)
I know you want a webapp, but Red Reader still works last time I checked. It's an open source android app. It still has API access since they don't make money. Perhaps something to use away from your computer.
