Unity Matchmaker currently supports Multiplay hosting, or a client-hosted solution provided by Unity, such as Relay and Distributed Authority. The team is working on extending support to third party hosting providers (including Multiplay by Rocket Science and others), and is aiming to deliver this support in advance of March 31st, 2026. Matchmaker will continue to work with Relay and Distributed Authority.
