Best Open-Source Alternatives to Discord

Discord dominates community chat but locks you in. OSS alternatives matter for community ownership, no ads/data harvesting, and self-hosting for privacy-sensitive groups.

TL;DR — top pick

Revolt

Revolt is the closest Discord clone — voice channels, custom emoji, bots, mobile apps. Modern UI, actively developed, fully open-source.
