The Arsse does not at this time have any first party clients. However, because The Arsse supports other protocols, most clients built for NextCloud News and Tiny Tiny RSS are compatible with The Arsse. Below are a few that we personally know of and have tested with The Arsse.

Excellent reader; one of the best on any platform.

Newsboat Linux, macOS

Terminal-based client.

Very basic client; now discontinued.

Very bland looking application, but it functions well.
