Seems like a missed opportunity to move away from proprietary solutions entirely. Teamspeak is self-hostable, but it is proprietary, supports limited numbers of users on the free tier, and presumably send telemetry to the proprietors even when "self-hosted."
Going by how little it is spoken on here I assume it is a localized phenomena, but the word of Fluxer.app is spreading among my spaces and it is open source and selfhostable and federation in the future.
The official instance and full time dev is funded by a cheaper discord nitro like premium sub.
It very recently became public and since that makes people think it is vibe coded I recommend reading the making off blog post https://blog.fluxer.app/
It isn't yet 1:1 with discord, no phone app yet, but it is by far the most discord like discord alternative (closer than Stoat), but open source and selfhostable.
