Disclaimer

Following instances skipped : number of users > 5.000, closed registration at the moment of checking, running old code, theme / description not understood due to language barrier or scarce description, long blocklists, experimental servers.

Note: new server additions welcome, however, this is a curated list for newcomers - for this reason second-level, human-friendly domain names will more likely be accepted than 3-level, long, unintelligible strings of letters.

Note: servers with closed registration may be placed only in “Notable mention” category, only if they represent well-known organizations or establishments.

Add your own themed instance via merge request. If your server already has many users, it will be nice of you to let other servers grow, for a healthier decentralization.
