Any world generator plugins that are free and look good?

I've been looking for a plugin like EpicWorldGenerator that is free. BiomeBundle is outdated and doesn't have any aquatic features. Any suggestions for plugins? I'm also willing to take the mod route, but I'd want it to be 1.15.1 compatible. Thanks!

You can probably find a cracked version of EpicWorldGenerator online. Have you tried BlackSpigot? (I'm not advertising, just letting them know about it)
