You're comment makes no sense. Matrix is a federated chat protocol, and works kind of like lemmy. Matrix itself has more in common with ActivityPub, the protocol that the fediverse uses. What's more comparable are the matrix clients.

There are many, many matrix clients to choose from, and even more instances, including the option to set up your own.

Which client? There's a lot more than Element, including clients like Nheko and Cinny.
