Yes. Aliucord is stuck in the past BUT is running the NATIVE version of the app (not the shitty slow electron one).

Vendetta Manager, discontinued but there is a fork that works. Up to date with discord.

vencord, hands down best modding client for the job. Just browse their catalog of avalabile plugins and get yourself a better experience ;D

As long as you're on discord, privacy is just not a thing. However, there was this 1 plugin i really liked, called File Name Randomizer or something along those lines. It would just rename any image you upload to the platform to someone generic. Other than that, there's the disabled telemetry that some clients come with, but that's the extent of what I know.
