Riot.im

Riot is a glossy Matrix client with an emphasis on performance and usability.

You can use it at https://riot.im/app, read more at https://riot.im and get the source from GitHub! Many public Matrix homeservers also host their own instance of Riot pre-configured to use that homeserver.

There is also a desktop version, which is available at riot.im. Taw has created RPM package builds for Fedora, CentOS, and Red Hat Enterprise Linux which are available via GitHub and FedoraCopr.

Josué Tille has contributed a Yunohost app.

Riot is built on top of matrix-react-sdk.
