Clients

The official set of clients follows the NATS Governance model and are managed under the nats-io GitHub organization.

There are also many community-developed clients with varying degrees of maturity and compatibility.

Forwards and backwards compatibility of the client protocol is a top priority so even if a client has not been updated for a while, it is likely to still work with recent versions of the server.

However to leverage all the latest server capabilities, it is recommended to always use the latest version of the client.
