There are plenty of third party apps for Lemmy on Android/iPhone or Web, but are there any decent apps built for desktop use? Is it just simply a matter of relying on a web interface currently, or are there any well rounded apps out there that are worth mentioning.
I use the basic frontend with Firefox.
A lot of extensions and userscripts support it it, and while there are are other frontends depending on your instance, I found them buggy.
You can find a lot of the extensions on communities that keep track of that. I use a few of extensions a lot, like Instance Assistant. Others look cool but I haven’t tried them much, like the multi-lemmy one
