Discord Alternatives
- Stoat;
- Matrix;
- Rocket.Chat;
- Zulip;
- Discourse.
Beginning with a phased global rollout to new and existing users in early March, users may be required to engage in an age-verification process to change certain settings or access sensitive content. This includes age-restricted channels, servers, or commands and select message requests.


Drop anything that’s not opensource and federated, except if you want to live the enshitification process over and over.
Matrix might be the closest to Discord. XMPP should also be considered.
