AkaziMC is a growing network of gamemodes that welcomes everyone. It supports crossplay between Java and Eagler, with version support from 1.12.2 up to 1.21.11, though 1.12.2 is heavily recommended for the best experience.
This is a community-focused server with no pay to win, active events, and a mix of survival, SMP, factions, PvP, and economy-style gameplay. The gamemodes are still expanding, so there is room for the server to keep growing with the community.
If you want to join, use the Java address for normal Minecraft or the Eaglercraft websocket if you're playing that way. AkaziMC is trying to build something solid around its players, not just toss up a server and leave it there.
