Moin is a voice-chat and screen-sharing application for friends and communities. People can choose a nickname rather than creating an account, join a temporary space or use persistent rooms on a community server. The apps are offered for Windows, macOS, Linux, iOS and Android, with screen sharing available on desktop. The site describes direct peer-to-peer voice connections and encrypted calls, including relay support when a network prevents a direct connection.
Moin's apps and core calling features are free. A community server can be self-hosted under the server licence, or users can pay Moin for managed hosting with a device-slot allowance. The homepage marks server-assisted screen forwarding as coming soon, rather than a current feature. Direct connections also mean other participants' devices can see a caller's IP address, an important distinction for people choosing a voice tool for public groups. Moin fits small communities seeking a focused calling experience without the account and feed structure of a broader social platform.
